opentelemetry-go: BSD kenv command not using absolute path enables PATH hijacking

CVE-2026-39883 / GHSA-hfvc-g4fc-pqhx

More information

Details

Summary

The fix for GHSA-9h8m-3fm2-qjrq (CVE-2026-24051) changed the Darwin ioreg command to use an absolute path but left the BSD kenv command using a bare name, allowing the same PATH hijacking attack on BSD and Solaris platforms.

Root Cause

sdk/resource/host_id.go line 42:

if result, err := r.execCommand("kenv", "-q", "smbios.system.uuid"); err == nil {

Compare with the fixed Darwin path at line 58:

result, err := r.execCommand("/usr/sbin/ioreg", "-rd1", "-c", "IOPlatformExpertDevice")

The execCommand helper at sdk/resource/host_id_exec.go uses exec.Command(name, arg...) which searches $PATH when the command name contains no path separator.

Affected platforms (per build tag in host_id_bsd.go:4): DragonFly BSD, FreeBSD, NetBSD, OpenBSD, Solaris.

The kenv path is reached when /etc/hostid does not exist (line 38-40), which is common on FreeBSD systems.

Attack
  1. Attacker has local access to a system running a Go application that imports go.opentelemetry.io/otel/sdk
  2. Attacker places a malicious kenv binary earlier in $PATH
  3. Application initializes OpenTelemetry resource detection at startup
  4. hostIDReaderBSD.read() calls exec.Command("kenv", ...) which resolves to the malicious binary
  5. Arbitrary code executes in the context of the application

Same attack vector and impact as CVE-2026-24051.

Suggested Fix

Use the absolute path:

if result, err := r.execCommand("/bin/kenv", "-q", "smbios.system.uuid"); err == nil {

On FreeBSD, kenv is located at /bin/kenv.

Severity

  • CVSS Score: 7.3 / 10 (High)
  • Vector String: CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

Release Notes

open-telemetry/opentelemetry-go (go.opentelemetry.io/otel/sdk)

v1.43.0: /v0.65.0/v0.19.0

Compare Source

Added

  • Add IsRandom and WithRandom on TraceFlags, and IsRandom on SpanContext in go.opentelemetry.io/otel/trace
    for W3C Trace Context Level 2 Random Trace ID Flag support. (#​8012)
  • Add service detection with WithService in go.opentelemetry.io/otel/sdk/resource. (#​7642)
  • Add DefaultWithContext and EnvironmentWithContext in go.opentelemetry.io/otel/sdk/resource to support plumbing context.Context through default and environment detectors. (#​8051)
  • Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc. (#​8038)
  • Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc. (#​8038)
  • Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc. (#​8038)

  • Add support for per-series start time tracking for cumulative metrics in go.opentelemetry.io/otel/sdk/metric.
    Set OTEL_GO_X_PER_SERIES_START_TIMESTAMPS=true to enable. (#​8060)
  • Add WithCardinalityLimitSelector for metric reader for configuring cardinality limits specific to the instrument kind. (#​7855)

Changed

  • Introduce the EMPTY Type in go.opentelemetry.io/otel/attribute to reflect that an empty value is now a valid value, with INVALID remaining as a deprecated alias of EMPTY. (#​8038)
  • Refactor slice handling in go.opentelemetry.io/otel/attribute to optimize short slice values with fixed-size fast paths. (#​8039)
  • Improve performance of span metric recording in go.opentelemetry.io/otel/sdk/trace by returning early if self-observability is not enabled. (#​8067)
