Release Notes

semgrep/semgrep (semgrep/semgrep)

v1.161.0

Compare Source

1.161.0 - 2026-04-22

### Added

• Scala 3.4+ trait parameters are now parsed correctly. (lang-73)

### Fixed

• Semgrep's HTTP requests no longer log URLs above the debug level; full request
  details remain available when running with SEMGREP_LOG_SRCS=cohttp.client. (ENGINE-2712)

v1.160.0

Compare Source

1.160.0 - 2026-04-16

### Added

• Scala: Added tree-sitter parser for improved parsing accuracy with pfff fallback. (LANG-255)
• pro: taint: Improved support for variadic functions (LANG-375)

### Fixed

• Fixed performance issues during parsing Semgrep rules containing emoji or
  other non-BMP Unicode characters. (gh-6070)
• Emit a warning when semgrep-core rule validation fails and falls back to JSON
  schema validation, alongside details of the failure. (gh-6071)

v1.159.0

Compare Source

1.159.0 - 2026-04-10

### Fixed

• Semgrep now reports an error instead of silently returning zero findings when target file discovery fails (e.g., due to a git ls-files failure). (ENGINE-2626)

v1.158.0

Compare Source

1.158.0 - 2026-04-09

### Added

• Added support for a supply chain hook for the Semgrep Plugin (supply-chain-hook)
• Computing taint configs, ~1/4-1/2 of the semgrep-core time in interfile scans, is now done in parallel according to the number of jobs (ENGINE-2649)
• Semgrep Pro interfile engine (--pro) taint analysis has been redesigned, significantly improving performance (estimated 20-40% improvement). This improvement introduces a slight change in how findings are generated, that may result in more true positives, or less false positives. To revert to previous behavior, pass --no-x-run-taint-once as a flag. (engine-2468)

### Changed

• semgrep-core macOS binaries are now dynamically linked to the system's libraries. (macos-binary-build)
• semgrep-core manylinux binaries are now dynamically linked to the system's glibc on glibc systems. This introduces a minimum glibc version requirement of >=2.35, which is satisfied in Ubuntu >=22.04, Debian >=12, RHEL >=10, and other glibc distributions with at least glibc 2.35. Linux systems running an older glibc will need to upgrade their OS. (manylinux-binary-build)
• The manylinux wheel is now tagged as manylinux_2_35_, reflecting a minimum
  requirement of glibc version 2.35. (manylinux-wheel-tag)
• semgrep-core musllinux binaries are now dynamically linked to the system's musl libc on musl systems. (musllinux-binary-build)
• The musllinux PyPI wheel is now tagged as musllinux_1_2_, reflecting a requirement
  of musl libc version 1.2. (musllinux-wheel-tag)
• The LSP and MCP servers now use the v2 config download endpoint by default when fetching rules from Semgrep AppSec Platform. Set SEMGREP_DISABLE_CONFIG_DOWNLOAD_V2=1 to fall back to the legacy endpoint. (SMS-2284)

### Fixed

• Fixed IDE login issues where network errors during token verification were incorrectly clearing the saved token. The LSP now distinguishes 401 Unauthorized (invalid token) from other errors (e.g. network failures), surfacing appropriate messages instead. (ide-login)
• Fixed SARIF taint trace output: step locations now use the correct file URI, and the full taint sink call trace is included in codeFlows. (engine-2570)
• The --x-mem-policy flag now propagates to the RPC subprocess, fixing memory tuning for dependency resolution and other RPC-based operations. (pylon-20772)

v1.157.0

Compare Source

1.157.0 - 2026-03-31

### Added

• pro: Improved taint tracking through lambda calls. (LANG-268)
• It is now possible to match a class name like in $C.getInstance(...), and then
  use metavariable-type on $C to check its type. (LANG-271)
• pro: Improve cross-file taint tracking for globals. (LANG-275)

### Changed

• Pro: Reduces redundant recomputation during inter-file taint analysis by serializing intermediate results to disk. (ENGINE-2582)
• pro: Improved golang module resolution. (code-9225)
• Supply Chain Analysis of npm package lock files now uses a proprietary OCaml-based parser, replacing the old Python version. The supply-chain functionality for these files is now available only to Semgrep Pro users. (gh-5658)

### Fixed

• Fix Rust parsing of "&raw" where "raw" is an identifier. (rust-parser-updated)
• Errors during target file discovery (e.g., permission errors, git failures) are now surfaced as warnings instead of being silently ignored. (ENGINE-2627)
• kotlin: Fixed bug parsing FQNs in metavariable-type. (LANG-271)
• Fixed requirements.txt parser silently dropping pinned dependencies that followed unpinned package names. (SC-3379)
• Prevented certain deeply nested aliengrep matches from segfaulting semgrep-core. (engine-2628)
• Fix Python parsing for files that contains empty strings (or quotes in docstrings) along with match statements. (gh-11287)
• Fix rule paths.include/paths.exclude filtering when a single file is passed as a scan target. Previously, path patterns like '/src/test//*.java' would not match because only the filename was used for filtering instead of the full project-relative path. (gh-11560)
• Pro: Improved type resolution in Scala (lang-79)
• Pro: Improved call resolution in Scala for parameterless methods (lang-80)

v1.156.0

Compare Source

1.156.0 - 2026-03-17

### Changed

• The Kotlin tree-sitter parser has been updated to the latest available grammar significantly improving Kotlin support in Semgrep. (kotlin-parser)

### Fixed

• Pro: Experimental interfile tainting for Ruby now disambiguates between variable accesses and zero-argument method calls. (engine-2556)
• Pro: Memoize tsconfig.json parsing to avoid redundant re-parsing across a project hierarchy. (engine-2596)
• Fixed a crash in semgrep ci when run in a git repo with no remote origin set (gh-11342)

v1.155.0

Compare Source

1.155.0 - 2026-03-11

### Added

• Added support for (agentic) hooks in Windsurf. (windsurf-hooks)
• scala: Improved support for Scala 3's optional braces. (LANG-218)
• Added PowerShell language support (beta) with parsing and pattern matching (lang-233)

### Changed

• Removed the experimental and undocumented command semgrep install-ci. (osemgrep-install-ci)

• Migrate from publishing a single Linux wheel with the platform tag musllinux_1_0_<arch>.manylinux2014_<arch> to publishing two separate wheels:

  • A wheel with the platform tag musllinux_1_0_
  • A wheel with the platform tag manylinux2014_

  (pypi-linux-tag)

### Fixed

• When performing parallel operations over a small number of input items, the
  engine no longer spawns more OCaml domains than we have items to process. This
  assists with resource utilisation. (engine-2588)
• Fixed: Prevent SessionStart hook crash when inject-secure-defaults receives empty stdin (JSONDecodeError). (engine-2592)
• Semgrep secret validation now times out after 30 seconds instead of 15 minutes. Additionally this timeout is configurable via the --secrets-timeout flag. (engine-2593)
• Fixed permission errors during lockfileless Java (Gradle) dependency resolution by invoking gradlew via sh when the executable bit is not set (gh-5747)

v1.154.0

Compare Source

1.154.0 - 2026-03-04

### Fixed

• Fix crash on Windows when running semgrep ci with --debug and no blocking findings. The Windows subprocess path incorrectly raised an exception for all pysemgrep exit codes (including 0), which was silently swallowed in normal mode but propagated as a fatal error when --debug was active. (ENGINE-2491)
• Changed default memory policy from "eager" to "balanced". Scan times should
  noticably improve; however, scans may use 5-10% additional memory. If running
  in a resource-constrained environment, consider setting the memory policy back
  to "aggressive". (engine-2055)
• When Semgrep decides which files to scan (targeting), it can take a long time (over 5 minutes) on very large repos (> 10k files). Semgrep will now parallelize this work according to the number of jobs passed (-j) (engine-2512)
• Fixed a performance issues where passing many scannign roots on the command
  line (e.g. semgrep scan $(git ls-files '*.py')) caused one semgrep-core
  subprocess to be spawned per file. Roots that are not directories are now
  handled directly in Python without any subprocess overhead. (gh-11404)
• Scala: Restored parse rate after mistaken bug introduced by implicit block parsing fix (lang-215)

v1.153.0

Compare Source

1.153.0 - 2026-02-25

### Added

• Semgrep core is now optimized with flambda (flambda)
• Scala: Support for for-yield (LANG-193)

### Fixed

• Scala: Fixed a parsing bug where subsequent calls in an implicit block would not
  be considered at the same scope, e.g.

  def f (a: t) =
    foo()
    bar()
  ``` (lang-194)

1.152.0 - 2026-02-17

### Added

• Hooks (for both Claude Code and Cursor) now pull custom rules from the registry (custom-rules-hooks)

• Turned on DNS rebinding protection for the MCP server (dns-check)

• Environment variables can now be passed to third-party package managers invoked as part of --allow-local-builds dependency resolution via the environment variable SEMGREP_LOCAL_BUILD_ENV, which accepts a JSON object with string keys and string values. (SC-3163)

• Memory management policies

  A memory policy defines how OCaml's garbage collector should be configured for
  a scan. There are two initial policies: "aggressive", the current behaviour,
  which trades longer scan times for lower memory use, and "balanced", which
  finds a middle ground between reclaiming heap memory in short order while
  limiting how often the garbage collector runs. The policy can be configured
  via the --x-mem-policy CLI flag for the pro engine; this flag is unused in
  the OSS engine. (engine-2055)

• Added experimental support for the OpenFGA authorization language. Thanks to Alex Useche (@​hex0punk) for the contribution! (gh-11347)

• Allows case insensitive string comparisons using lower() and upper() like this:

  - metavariable-comparison:
      metavariable: $VALUE
      comparison: upper(str($VALUE)) == "SEMGREP"
  

  (gh-11502)

• Blocking findings that are outputted in the CI output are now labelled as such. (#​4394)

### Changed

• pro: There should be fewer FNs when the max number of fields to track per object
  is reached. (code-9224)
• Remove legacy combined symbol analysis computation and upload in favor of per-subproject symbol analysis (sc-3153)

### Fixed

• pro: Improved accuracy of taint tracking through assignments, this will help
  reduce FPs in some cases. (code-9220)
• When receiving a 429 or 5xx from the Semgrep app, the CLI will wait for a
  longer period of time before retrying the request, to spread out requests
  during periods of app instability. (engine-2550)

1.151.0 - 2026-02-04

Added

• Added progress indicators for symbol analysis calculation and upload during CI scans (sc-3103)

Fixed

• bumped glom to at least version 23.3, which includes a fix to a SyntaxWarning
  warning log. (gh-11460)
• Semgrep no longer prints info log lines from semgrep-core RPC calls when --trace is passed and --debug isn't (loglines)
• Fixed the README not appearing in built wheels. (wheelreadme)

1.150.0 - 2026-01-29

Added

• Connecting to the Semgrep MCP server via streamableHttp now requires OAuth. (saf-2453)

Changed

• Migrated from pipenv to uv for ./cli package management (uv)

Fixed

• pro: Improved virtual method resolution in Scala (code-9213)
• Improved performance for supply chain scans by reducing pre-computation when printing the scan status. This results in slightly less information being displayed in the case that there are no rules to run. (gh-5436)
• Supply Chain Analysis: fixed version range matching for NPM packages with versions containing a prerelease identifier such as -alpha in 1.2.3-alpha. (sc-3001)

1.149.0 - 2026-01-21

Added

• Added a warning in --debug mode when a user runs a parallel scan with a larger
  value for -j/--jobs than the number of CPUs we detect the host has made
  available to Semgrep. Additionally, a suggested starting value for -j/--jobs
  is reported to give the user a place to start tuning their scan. (saf-2474)
• Upload symbol analysis on a per-subproject basis during supply chain scans. (sc-3038)

Changed

• The MCP server no longer supports SSE transport. (saf-2462)

Fixed

• pro: Improved virtual method resolution in Java (code-9210)
• pro: Improved virtual method resolution in Scala (code-9212)
• Improve performance of scan planning, a part of the Python CLI, by reducing
  the cost of re-hashing Target objects. Performance should improve on
  large repo scans proportionally to the number of files in the repo. (gh-5407)
• semgrep ci no longer applies autofixes to disk, even when the "Suggest autofixes" toggle in the app is enabled. (saf-2446)

1.148.0 - 2026-01-14

Added

• Performance: subproject discovery in Supply Chain scans is no longer
  significantly slowed down by the presence of Git-untracked files
  resulting in faster diff scans in such cases. (sc-subproject-speedup)

Fixed

• pro: Improved virtual method resolution in Java (code-9174)
• pro: Improved handling of parse errors during inter-file analysis. Now, these
  errors should be adequately reported back to users and in the JSON output. (code-9216)
• Dataflow now accounts for Python for/else and while/else loops. (gh-8405)
• Fix rare "bad file descriptor" when performing Git operations on Windows (saf-2358)

1.147.0 - 2026-01-07

Added

• Gradle lockfiles of the form gradle*.lockfile are now supported. Previously, only lockfiles named exactly gradle.lockfile were supported. (SC-2999)
• semgrep login now supports a --force flag, which ignores existing tokens and starts a new login session. The MCP setup workflow has been updated to use --force too. (saf-2392)

Fixed

• Deduplication should now pick the exact same findings across scans. Previously,
  findings were always equivalent, but not guaranteed to be exactly the same
  (e.g. metavariable bindings could differ). Depending on the rule and target code,
  this could cause findings' fingerprints to change from one scan to another, thus
  leading to finding flakiness and "cycling" in Semgrep App. Note that when
  upgrading to this Semgrep version, you may see different (but equivalent) findings
  wrt your current Semgrep version in the first scan, one more time. However, in
  subsequent scans/upgrades, this problem should go away or at least be greatly
  reduced. (saf-2304)

1.146.0 - 2025-12-17

Added

• Added support for Cursor post-code-generation hooks via new record-file-edit and stop-cli-scan semgrep mcp flags (cursor-hooks)
• Added skipped_paths field to CI scan results to report files that failed to scan due to errors (timeout, OOM, etc.), preventing the app from incorrectly marking findings in those files as fixed (gh-5122)
• Symbol analysis, if enabled, now runs for Supply Chain only scans when calling semgrep ci. (sc-2927)

Changed

• Semgrep's Docker image base has been bumped from Alpine Linux 3.22 to 3.23 (docker-version)
• bumped the mcp python-sdk from 1.16.0 to 1.23.3 (mcp-version)
• pro: [experimental] enabling and disabling transitive reachability
  analysis in semgrep ci regardless of app settings is now possible with
  --x-enable-transitive-reachability (or --x-tr)
  and --x-disable-transitive-reachability. (tr-flags)

Fixed

• The PHP AST now distinguishes between if statements with no else clause and those with an explicit but empty else {}. (gh-11330)
• git-lfs objects are now excluded from baseline scans, as they are usually binary files, or simply too large to scan. (saf-2020)
• Fix a OCaml stdlib bug that would cause nondeterministic UnixErrors on Windows under the multicore runtime due to a race condition in the socketpair implementation (saf-2316)
• Fixed an issue that in rare cases could lead timeouts to be mishandled. This typically manifested only through slightly different warning messages, but it is possible that more serious consequences could have occasionally resulted. (saf-2368)
• Fixed symbol analysis incorrectly analyzing all files instead of only the relevant language files per ecosystem. (sc-3020)

1.145.2 - 2025-12-12

No significant changes.

1.145.1 - 2025-12-11

No significant changes.

1.145.0 - 2025-12-04

Added

• Added optional user-prompting for classifying findings as true/false positives via MCP Elicitation in the MCP server (behind SEMGREP_FINDINGS_ELICITATION_ENABLED, off by default). (elicitation)
• Added hook to inject secure-by-default library recommendations into Claude Code Agent context. (secure-defaults-hook)

Changed

• Symbol analysis upload now runs before scan completion to ensure it is available during initial scan postprocessing. (sc-2933)

Fixed

• Fix issue that could lead to validation failures for certain well-formed rules, such as those with emoji in their messages. (incid-293)
• The correct range for let ... in expressions in OCaml is now reported. Previously, the location of the let was omitted. This is mainly relevant for autofix. (ocaml-let)
• Debug log lines concerning telemetry collection that are only relevant inside
  Semgrep's managed scanning environment are not emitted if a scan runs outside
  that environment. (saf-2321)
• pro: in 1.144.0 interfile scans no longer default to -j 1; instead, the number of available CPUs on the system was used to inform how many jobs should be spawned. This caused a change in timeouts due to how time is measured for certain parts of the pro engine. This change has now been reverted (saf-default-jobs)

1.144.1 - 2025-12-04

Fixed

• Fix issue that could lead to validation failures for certain well-formed rules, such as those with emoji in their messages. (incid-293)
• pro: in 1.144.0 interfile scans no longer default to -j 1; instead, the number of available CPUs on the system was used to inform how many jobs should be spawned. This caused a change in timeouts due to how time is measured for certain parts of the pro engine. This change has now been reverted (saf-default-jobs)

1.144.0 - 2025-11-19

Fixed

• pro: interfile scans no longer default to -j 1; instead, the number of
  available CPUs on the system is polled as part of a heuristic to determine how
  many threads should be spawned. (gh-4952)
• Semgrep will no longer rarely crash when --trace is passed. (incid-280)

1.143.3 - 2025-11-25

No significant changes.

1.143.2 - 2025-11-25

Fixed

• Fix issue that could lead to validation failures for certain well-formed rules, such as those with emoji in their messages. (incid-293)

1.143.1 - 2025-11-14

Fixed

• Semgrep will no longer rarely crash when --trace is passed. (incid-280)

1.143.0 - 2025-11-12

Added

• Dataflow will now understand empty block expressions as having unit value in
  more instances. (code-9141)
• Parallel scans will now use shared-memory parallelism using multicore OCaml
  domains, rather than the legacy fork-join approach. Users can opt into the
  legacy method with the --x-parmap CLI flag, and this deprecates the --x-eio
  flag (since it is now the default behaviour). (saf-2271)
• Add -k/ --hook flag to enable Semgrep scans via Claude Code Agent post-tool hooks (saf-2279)

Fixed

• When running semgrep scan or semgrep ci, the progress bar now always ends at 100%. (SAF-2079)
• Pro: fixed various bugs relating to Scala match expression handling in dataflow
  analysis (e.g., some branches being misordered, especially when matching
  multiple variables against non-integer literal patterns). (code-9144)
• Semgrep will now emit better error messages when exceptions are raised at the beginning or end of scan (exit-message)
• Enabled taint tracking into Goroutines, by treating them as regular Go function calls. (gh-11207)
• Fixed missing Rust type alias translation. We can now
  accurately match the () type in a type declaration. (gh-11283)
• fixed MCP semgrep_findings tool to accept single issue_type parameter and corrected identity string role parsing (saf-2282)

1.142.0 - 2025-10-30

Added

• Pro: improved taint handling of match expressions in Scala. In examples like

  val x = taint match {
      case Some(t) => t
      case None => return "example"
  }

  dataflow should now track taint from taint to x. (code-9085)
• pro: scala: http4s-specific support for case $M -> ... :? ... +& test +& ... => ... patterns. (code-9131)

Fixed

• Supply Chain subproject resolution table is now shown even when no subprojects were successfully resolved (SC-2492)
• UV lockfiles that include editable and local dependencies without versions are now parsed correctly. The unversioned dependencies will be ignored. (SC-2888)
• Failures in parsing UV lockfiles are now correctly reported as "Failed" rather than "Unsupported" (SC-2895)
• build.gradle.kts files now resolve correctly when --allow-local-builds is passed. (SC-2899)
• Rule parsing in 1.139.0 was switched to happen solely in semgrep-core. This caused some users to exit with code 7, so this change has been reverted. (saf-2265)

  upgrading to this Semgrep version, you may see different (but equivalent) findings
  wrt your current Semgrep version in the first scan, one more time. However, in
  subsequent scans/upgrades, this problem should go away or at least be greatly
  reduced. (saf-2304)

1.146.0 - 2025-12-17

Added

• Added support for Cursor post-code-generation hooks via new record-file-edit and stop-cli-scan semgrep mcp flags (cursor-hooks)
• Added skipped_paths field to CI scan results to report files that failed to scan due to errors (timeout, OOM, etc.), preventing the app from incorrectly marking findings in those files as fixed (gh-5122)
• Symbol analysis, if enabled, now runs for Supply Chain only scans when calling semgrep ci. (sc-2927)

Changed

• Semgrep's Docker image base has been bumped from Alpine Linux 3.22 to 3.23 (docker-version)
• bumped the mcp python-sdk from 1.16.0 to 1.23.3 (mcp-version)
• pro: [experimental] enabling and disabling transitive reachability
  analysis in semgrep ci regardless of app settings is now possible with
  --x-enable-transitive-reachability (or --x-tr)
  and --x-disable-transitive-reachability. (tr-flags)

Fixed

• The PHP AST now distinguishes between if statements with no else clause and those with an explicit but empty else {}. (gh-11330)
• git-lfs objects are now excluded from baseline scans, as they are usually binary files, or simply too large to scan. (saf-2020)
• Fix a OCaml stdlib bug that would cause nondeterministic UnixErrors on Windows under the multicore runtime due to a race condition in the socketpair implementation (saf-2316)
• Fixed an issue that in rare cases could lead timeouts to be mishandled. This typically manifested only through slightly different warning messages, but it is possible that more serious consequences could have occasionally resulted. (saf-2368)
• Fixed symbol analysis incorrectly analyzing all files instead of only the relevant language files per ecosystem. (sc-3020)

1.145.2 - 2025-12-12

No significant changes.

1.145.1 - 2025-12-11

No significant changes.

1.145.0 - 2025-12-04

Added

• Added optional user-prompting for classifying findings as true/false positives via MCP Elicitation in the MCP server (behind SEMGREP_FINDINGS_ELICITATION_ENABLED, off by default). (elicitation)
• Added hook to inject secure-by-default library recommendations into Claude Code Agent context. (secure-defaults-hook)

Changed

• Symbol analysis upload now runs before scan completion to ensure it is available during initial scan postprocessing. (sc-2933)

Fixed

• Fix issue that could lead to validation failures for certain well-formed rules, such as those with emoji in their messages. (incid-293)
• The correct range for let ... in expressions in OCaml is now reported. Previously, the location of the let was omitted. This is mainly relevant for autofix. (ocaml-let)
• Debug log lines concerning telemetry collection that are only relevant inside
  Semgrep's managed scanning environment are not emitted if a scan runs outside
  that environment. (saf-2321)
• pro: in 1.144.0 interfile scans no longer default to -j 1; instead, the number of available CPUs on the system was used to inform how many jobs should be spawned. This caused a change in timeouts due to how time is measured for certain parts of the pro engine. This change has now been reverted (saf-default-jobs)

1.144.1 - 2025-12-04

Fixed

• Fix issue that could lead to validation failures for certain well-formed rules, such as those with emoji in their messages. (incid-293)

1.144.0 - 2025-11-19

Fixed

• pro: interfile scans no longer default to -j 1; instead, the number of
  available CPUs on the system is polled as part of a heuristic to determine how
  many threads should be spawned. (gh-4952)
• Semgrep will no longer rarely crash when --trace is passed. (incid-280)

1.143.3 - 2025-11-25

No significant changes.

1.143.2 - 2025-11-25

Fixed

• Fix issue that could lead to validation failures for certain well-formed rules, such as those with emoji in their messages. (incid-293)

1.143.1 - 2025-11-14

Fixed

• Semgrep will no longer rarely crash when --trace is passed. (incid-280)

1.143.0 - 2025-11-12

Added

• Dataflow will now understand empty block expressions as having unit value in
  more instances. (code-9141)
• Parallel scans will now use shared-memory parallelism using multicore OCaml
  domains, rather than the legacy fork-join approach. Users can opt into the
  legacy method with the --x-parmap CLI flag, and this deprecates the --x-eio
  flag (since it is now the default behaviour). (saf-2271)
• Add -k/ --hook flag to enable Semgrep scans via Claude Code Agent post-tool hooks (saf-2279)

Fixed

• When running semgrep scan or semgrep ci, the progress bar now always ends at 100%. (SAF-2079)
• Pro: fixed various bugs relating to Scala match expression handling in dataflow
  analysis (e.g., some branches being misordered, especially when matching
  multiple variables against non-integer literal patterns). (code-9144)
• Semgrep will now emit better error messages when exceptions are raised at the beginning or end of scan (exit-message)
• Enabled taint tracking into Goroutines, by treating them as regular Go function calls. (gh-11207)
• Fixed missing Rust type alias translation. We can now
  accurately match the () type in a type declaration. (gh-11283)
• fixed MCP semgrep_findings tool to accept single issue_type parameter and corrected identity string role parsing (saf-2282)

1.142.0 - 2025-10-30

Added

• Pro: improved taint handling of match expressions in Scala. In examples like

  val x = taint match {
      case Some(t) => t
      case None => return "example"
  }

  dataflow should now track taint from taint to x. (code-9085)
• pro: scala: http4s-specific support for case $M -> ... :? ... +& test +& ... => ... patterns. (code-9131)

Fixed

• Supply Chain subproject resolution table is now shown even when no subprojects were successfully resolved (SC-2492)
• UV lockfiles that include editable and local dependencies without versions are now parsed correctly. The unversioned dependencies will be ignored. (SC-2888)
• Failures in parsing UV lockfiles are now correctly reported as "Failed" rather than "Unsupported" (SC-2895)
• build.gradle.kts files now resolve correctly when --allow-local-builds is passed. (SC-2899)
• Rule parsing in 1.139.0 was switched to happen solely in semgrep-core. This caused some users to exit with code 7, so this change has been reverted. (saf-2265)

v1.150.0

Compare Source

### Added

• Semgrep core is now optimized with flambda (flambda)
• Scala: Support for for-yield (LANG-193)

### Fixed

• Scala: Fixed a parsing bug where subsequent calls in an implicit block would not
  be considered at the same scope, e.g.

  def f (a: t) =
    foo()
    bar()
  ``` (lang-194)
  

1.152.0 - 2026-02-17

### Added

• Hooks (for both Claude Code and Cursor) now pull custom rules from the registry (custom-rules-hooks)

• Turned on DNS rebinding protection for the MCP server (dns-check)

• Environment variables can now be passed to third-party package managers invoked as part of --allow-local-builds dependency resolution via the environment variable SEMGREP_LOCAL_BUILD_ENV, which accepts a JSON object with string keys and string values. (SC-3163)

• Memory management policies

  A memory policy defines how OCaml's garbage collector should be configured for
  a scan. There are two initial policies: "aggressive", the current behaviour,
  which trades longer scan times for lower memory use, and "balanced", which
  finds a middle ground between reclaiming heap memory in short order while
  limiting how often the garbage collector runs. The policy can be configured
  via the --x-mem-policy CLI flag for the pro engine; this flag is unused in
  the OSS engine. (engine-2055)

• Added experimental support for the OpenFGA authorization language. Thanks to Alex Useche (@​hex0punk) for the contribution! (gh-11347)

• Allows case insensitive string comparisons using lower() and upper() like this:

  - metavariable-comparison:
      metavariable: $VALUE
      comparison: upper(str($VALUE)) == "SEMGREP"
  

  (gh-11502)

• Blocking findings that are outputted in the CI output are now labelled as such. (#​4394)

### Changed

• pro: There should be fewer FNs when the max number of fields to track per object
  is reached. (code-9224)
• Remove legacy combined symbol analysis computation and upload in favor of per-subproject symbol analysis (sc-3153)

### Fixed

• pro: Improved accuracy of taint tracking through assignments, this will help
  reduce FPs in some cases. (code-9220)
• When receiving a 429 or 5xx from the Semgrep app, the CLI will wait for a
  longer period of time before retrying the request, to spread out requests
  during periods of app instability. (engine-2550)

1.151.0 - 2026-02-04

Added

• Added progress indicators for symbol analysis calculation and upload during CI scans (sc-3103)

Fixed

• bumped glom to at least version 23.3, which includes a fix to a SyntaxWarning
  warning log. (gh-11460)
• Semgrep no longer prints info log lines from semgrep-core RPC calls when --trace is passed and --debug isn't (loglines)
• Fixed the README not appearing in built wheels. (wheelreadme)

1.150.0 - 2026-01-29

Added

• Connecting to the Semgrep MCP server via streamableHttp now requires OAuth. (saf-2453)

Changed

• Migrated from pipenv to uv for ./cli package management (uv)

Fixed

• pro: Improved virtual method resolution in Scala (code-9213)
• Improved performance for supply chain scans by reducing pre-computation when printing the scan status. This results in slightly less information being displayed in the case that there are no rules to run. (gh-5436)
• Supply Chain Analysis: fixed version range matching for NPM packages with versions containing a prerelease identifier such as -alpha in 1.2.3-alpha. (sc-3001)

1.149.0 - 2026-01-21

Added

• Added a warning in --debug mode when a user runs a parallel scan with a larger
  value for -j/--jobs than the number of CPUs we detect the host has made
  available to Semgrep. Additionally, a suggested starting value for -j/--jobs
  is reported to give the user a place to start tuning their scan. (saf-2474)
• Upload symbol analysis on a per-subproject basis during supply chain scans. (sc-3038)

Changed

• The MCP server no longer supports SSE transport. (saf-2462)

Fixed

• pro: Improved virtual method resolution in Java (code-9210)
• pro: Improved virtual method resolution in Scala (code-9212)
• Improve performance of scan planning, a part of the Python CLI, by reducing
  the cost of re-hashing Target objects. Performance should improve on
  large repo scans proportionally to the number of files in the repo. (gh-5407)
• semgrep ci no longer applies autofixes to disk, even when the "Suggest autofixes" toggle in the app is enabled. (saf-2446)

1.148.0 - 2026-01-14

Added

• Performance: subproject discovery in Supply Chain scans is no longer
  significantly slowed down by the presence of Git-untracked files
  resulting in faster diff scans in such cases. (sc-subproject-speedup)

Fixed

• pro: Improved virtual method resolution in Java (code-9174)
• pro: Improved handling of parse errors during inter-file analysis. Now, these
  errors should be adequately reported back to users and in the JSON output. (code-9216)
• Dataflow now accounts for Python for/else and while/else loops. (gh-8405)
• Fix rare "bad file descriptor" when performing Git operations on Windows (saf-2358)

1.147.0 - 2026-01-07

Added

• Gradle lockfiles of the form gradle*.lockfile are now supported. Previously, only lockfiles named exactly gradle.lockfile were supported. (SC-2999)
• semgrep login now supports a --force flag, which ignores existing tokens and starts a new login session. The MCP setup workflow has been updated to use --force too. (saf-2392)

Fixed

• Deduplication should now pick the exact same findings across scans. Previously,
  findings were always equivalent, but not guaranteed to be exactly the same
  (e.g. metavariable bindings could differ). Depending on the rule and target code,
  this could cause findings' fingerprints to change from one scan to another, thus
  leading to finding flakiness and "cycling" in Semgrep App. Note that when
  upgrading to this Semgrep version, you may see different (but equivalent) findings
  wrt your current Semgrep version in the first scan, one more time. However, in
  subsequent scans/upgrades, this problem should go away or at least be greatly
  reduced. (saf-2304)
