chore(docker): clear most CVEs in published image (npm/pnpm/uuid + drop curl)

[JohnMcLear]

Summary

Cuts published-image vulnerabilities reported by docker scout from 18 (0C/4H/13M/1L) across 8 packages → 12 (0C/2H/9M/1L) across 3 packages, locally verified against etherpad/etherpad:2.7.2.

The three remaining flagged packages — curl/libcurl, git, busybox — are all upstream Alpine 3.23 packages currently marked not fixed. libcurl is a transitive dep of git and can't be removed independently; the curl advisories scout still attributes to it are SMB-protocol use-after-frees that are unreachable from any code we ship.

Changes

• Provision pnpm via corepack and remove bundled npm. The node:22-alpine base ships npm@10.9.7 whose bundled transitives carry CVEs we don't need at runtime: picomatch 4.0.3 (CVE-2026-33671 high, CVE-2026-33672) and brace-expansion 2.0.2 (CVE-2026-33750). Corepack provisions pnpm directly and we delete /usr/local/lib/node_modules/npm plus its CLI shims. Clears 1 high + 1 medium.
• Bump PnpmVersion 10.28.2 → 10.33.2. Aligns with the workflow's pnpm/action-setup pinning and brings pnpm's bundled brace-expansion to 5.0.5 (was 5.0.4 / CVE-2026-33750). Clears 1 medium.
• Add uuid@<14.0.0 → >=14.0.0 override. Fixes GHSA-w5hq-g745-h8pq. Lockfile resolves to uuid@14.0.0. Clears 1 medium.
• Drop curl from runtime apk add and switch HEALTHCHECK to wget. curl was only invoked by the HEALTHCHECK and a couple of dev/CI scripts that don't run in the container. wget (busybox built-in) replaces it. Side-effect: clears nghttp2 (CVE-2026-27135 high), which was a curl-CLI runtime dep.
• HEALTHCHECK URL localhost → 127.0.0.1. Alpine/musl resolves localhost to ::1 first and Etherpad only binds IPv4 — was producing `Connection refused` until the IPv4 fallback timed out.

Test plan

• `docker build --target production` passes
• container starts and reports `healthy`
• `docker scout cves` confirms reduction (18 → 12 CVEs, 8 → 3 packages)
• CI: docker.yml `build-test`, `build-test-db-drivers`, and full test suites green

1. Corepack pnpm prepare failure ✓ Resolved 🐞 Bug ☼ Reliability

Description

The Dockerfile now runs corepack prepare pnpm@${PnpmVersion} --activate without first updating
corepack; this repo already documents that Node 22’s bundled corepack can reject newer pnpm versions
due to a stale signing-key list, which would fail the Docker build at that step. This occurs in both
the adminbuild and build stages, so a rejection would block image builds entirely.

Code

Dockerfile[R13-16]

+# Use corepack to provision pnpm and drop the bundled npm — its older
+# transitives (picomatch, brace-expansion) carry CVEs we don't otherwise need.
+RUN corepack enable && corepack prepare pnpm@${PnpmVersion} --activate && \
+    rm -rf /usr/local/lib/node_modules/npm /usr/local/bin/npm /usr/local/bin/npx

Evidence

Dockerfile uses corepack to prepare pnpm (and removes npm afterwards), while snap packaging
explicitly upgrades corepack first because the Node 22-bundled corepack may reject newer pnpm
releases; the same corepack rejection would fail the Docker build at corepack prepare.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The Dockerfile provisions pnpm via `corepack prepare pnpm@${PnpmVersion} --activate` but does not refresh corepack first. The repo’s snap build already documents that Node 22’s bundled corepack can reject newer pnpm versions due to stale signing keys; if that happens here, the image build fails at `corepack prepare`.
### Issue Context
- This is done in *two* stages (`adminbuild` and `build`).
- The snap packaging flow addresses the exact failure mode by upgrading corepack before running `corepack prepare`.
### Fix Focus Areas
- Dockerfile[12-20]
- Dockerfile[98-109]
- snap/snapcraft.yaml[111-118]
### Implementation direction
- In both Dockerfile stages, install/upgrade corepack (using the bundled npm *before* deleting npm), then run `corepack enable` + `corepack prepare pnpm@${PnpmVersion} --activate`, then remove npm/npx as you do today.
- Keep/extend the comment to explain why corepack is upgraded first (mirror the rationale in `snap/snapcraft.yaml`).

2. Unpinned corepack version 🐞 Bug ⛨ Security

Description

The Dockerfile installs corepack via npm install -g corepack@latest, so rebuilding the same
Dockerfile at different times can pull different corepack versions and change behavior or break
builds. This reduces reproducibility and increases supply-chain risk for the published image build
pipeline.

Code

Dockerfile[R18-20]

+RUN npm install -g corepack@latest && \
+    corepack enable && corepack prepare pnpm@${PnpmVersion} --activate && \
+    rm -rf /usr/local/lib/node_modules/npm /usr/local/bin/npm /usr/local/bin/npx

Evidence

Both the admin build stage and the main build stage install Corepack from the floating latest tag,
so the resulting image contents depend on build time rather than the repo state.

Dockerfile[12-20]
Dockerfile[102-114]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The Dockerfile installs `corepack` from `corepack@latest`, which is non-deterministic across rebuilds.
### Issue Context
`latest` will resolve to different versions over time, so the same git SHA can produce different images.
### Fix Focus Areas
- Dockerfile[12-20]
- Dockerfile[102-114]
### Suggested fix
- Introduce an explicit version (e.g. `ARG CorepackVersion=...`) and use `npm install -g corepack@${CorepackVersion}` in both stages.
- Consider pinning to the same version you validated locally/CI (and keep the pnpm version pin you already have).

3. Forced uuid major upgrade ✓ Resolved 🐞 Bug ☼ Reliability

Description

The new pnpm override forces uuid from =14 across the workspace, changing the resolved uuid
version used by @azure/msal-node. Because this bypasses downstream semver constraints, it can
break any runtime path that loads @azure/msal-node if it is incompatible with uuid@14.

Code

package.json[77]

+      "uuid@<14.0.0": ">=14.0.0",

Evidence

The repo-wide override explicitly forces uuid to 14+, and the lockfile shows
@azure/msal-node@5.1.4 now depends on uuid: 14.0.0, so any incompatibility will surface when
msal-node is loaded.

package.json[54-80]
pnpm-lock.yaml[18-26]
pnpm-lock.yaml[6033-6044]
pnpm-lock.yaml[5559-5562]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The pnpm override forces a major `uuid` upgrade broadly (`>=14.0.0`), which can unintentionally pull newer `uuid` versions later and may violate transitive dependencies’ expectations.
### Issue Context
Lockfile currently resolves `uuid@14.0.0` for `@azure/msal-node`, but the override allows future automatic upgrades beyond 14.0.0 without review.
### Fix Focus Areas
- package.json[54-80]
- pnpm-lock.yaml[18-26]
### Suggested fix
- Change the override value from `>=14.0.0` to an exact pin (e.g. `14.0.0`) or a tightly-scoped range you’re comfortable supporting.
- Add/extend CI coverage to exercise/import the relevant Azure/MSAL path if it is a supported runtime feature.

4. curl removed from image 📘 Rule violation ⚙ Maintainability

Description

The PR removes the curl package from the runtime image, which can break existing user workflows or
automation that execs into the container and relies on curl being present. This is a
backwards-incompatible change to the published container environment without an in-repo
compatibility/mitigation mechanism.

Code

Dockerfile[103]

-        curl \

Evidence

PR Compliance ID 2 requires avoiding backwards-incompatible changes without mitigation; the
Dockerfile explicitly removes curl from the installed runtime packages.

Dockerfile[103-103]
Best Practice: Repository guidelines

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The runtime Docker image no longer installs `curl`, which can be a backwards-incompatible change for users who rely on `curl` being available inside the container.
## Issue Context
This PR intentionally drops `curl` to reduce CVEs, but the published image environment is part of the user-facing surface area; removing commonly-used tooling can break downstream scripts.
## Fix Focus Areas
- Dockerfile[99-109]
(Consider a mitigation such as an opt-in build arg to include `curl`, a separate image/tag variant, and/or documenting the removal prominently in existing Docker image documentation/release notes.)

5. npm/npx removed from image 📘 Rule violation ⚙ Maintainability

Description

The PR deletes the npm and npx binaries and the bundled npm installation from the image, which
can break existing workflows that expect npm tooling to exist in the published container. This is
a backwards-incompatible change to the container environment without an in-repo
compatibility/mitigation mechanism.

Code

Dockerfile[103]

+    rm -rf /usr/local/lib/node_modules/npm /usr/local/bin/npm /usr/local/bin/npx && \

Evidence

PR Compliance ID 2 requires avoiding backwards-incompatible changes without mitigation; the
Dockerfile explicitly removes /usr/local/lib/node_modules/npm and the npm/npx shims from the
image.

Dockerfile[102-103]
Best Practice: Repository guidelines

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The Docker image no longer includes `npm`/`npx` due to explicit deletion of the bundled npm installation and shims, which can be backwards-incompatible for users.
## Issue Context
This PR removes npm to reduce CVEs and standardize on pnpm via corepack, but users may have scripts that run `npm` inside the container (for debugging, plugin installation, etc.).
## Fix Focus Areas
- Dockerfile[10-16]
- Dockerfile[99-109]
(Consider a mitigation such as providing an opt-in build arg or separate image/tag that retains `npm`/`npx`, and/or documenting the removal prominently in the Docker image docs/release notes.)

Qodo review responses:

1. Corepack pnpm prepare failure (Bug): fixed in 5a8561f — npm install -g corepack@latest now runs in both stages before corepack prepare, mirroring the snap/snapcraft.yaml workaround for nodejs/corepack#612.

2. curl removed from image (Rule violation): intentional. The runtime curl CLI was unused except by the HEALTHCHECK (now wget — busybox built-in, always present). Dropping it eliminates 10 CVEs (1H/8M/1L) plus its nghttp2 dep. Operators who exec into the container for ad-hoc HTTP can still use wget; if they specifically need curl they can apk add curl post-up. Will note in the next release's docker section.

3. npm/npx removed from image (Rule violation): intentional. Etherpad uses pnpm exclusively at runtime (bin/installDeps.sh, pnpm run prod, plugin install via pnpm run plugins i); npm in the published container was dead weight that carried CVEs in its bundled transitives (picomatch 4.0.3, brace-expansion 2.0.2). pnpm is provisioned via corepack, so the package-manager surface is preserved — just on the modern tool. Same release-note disclosure path.

Persistent review updated to latest commit 5a8561f

[JohnMcLear]

Re-checking the rule-violation findings after pushing 5a8561f — Qodo's reply was paused at the free-tier limit, but I went back through them and added the missing mitigation:

#2 (curl) and #3 (npm/npx): documented in CHANGELOG.md 2.7.3 breaking changes (commit f42ffef). Operators who exec into the container and need either tool can apk add curl or fall back to the already-present busybox wget / pnpm. That closes the "backwards-incompatible change without mitigation" gap that PR Compliance ID 2 is asking for.
