The GitHub runner's Python toolcache ships setuptools 79.0.1, which
pip-audit flags for PYSEC-2026-3447 (fixed in 83.0.0), failing the
blocking Backend Security job. A fix version exists, so upgrade
setuptools in the install step rather than --ignore-vuln. Applied to
both ci.yml (blocking) and security.yml (scheduled scan).
GitHub forces Node-20 actions to run on Node 24 starting 2026-06-02 and
removes Node 20 from the runner on 2026-09-16. Bumping each action to
its first Node-24 major now gets us ahead of both deadlines and silences
the deprecation warnings already firing in every CI run.
Bumps (across ci.yml, security.yml, codeql.yml, auto-label-area.yml,
issue-closed.yml, stale.yml):
- actions/checkout v4 -> v6
- actions/setup-python v5 -> v6
- actions/setup-node v4 -> v6
- actions/cache v4 -> v5
- actions/upload-artifact v4 -> v7
- actions/github-script v7 -> v9
- actions/stale v9 -> v10
- docker/setup-buildx v3 -> v4
- docker/build-push v5 -> v7
Verified each major's breaking-change notes against our usage:
- setup-node v6 limits auto-cache to npm only; we already pass
cache: 'npm' explicitly, so nothing changes.
- github-script v9 drops require('@actions/github'); none of our
scripts use it (only require('fs') and the injected github/context
globals).
- setup-buildx v4 removes deprecated inputs; we call it with no
inputs.
- build-push v6 enables build summaries by default; informational,
can disable via DOCKER_BUILD_SUMMARY=false env if it gets noisy.
codeql-action stays on v4 (already runs on Node 24). Trivy and
github-repo-stats are Docker actions and aren't affected by the
Node-20 deprecation.
- requirements.txt: pin idna>=3.15 to clear ReDoS in idna.encode() on
crafted Unicode payloads. Transitive via anyio/httpx/requests/yarl,
so the explicit floor stops a future downstream loosening from
silently downgrading us.
- security.yml: permanently --ignore-vuln CVE-2025-45768 (PyJWT). The
advisory is disputed by the maintainers — "key length is chosen by
the application" — and no fix version exists. Bambuddy is safe:
auto-generates secrets via secrets.token_urlsafe(64) and rejects
file-loaded secrets shorter than 32 chars (auth.py:177, :184).
- security.yml: drop the stale Pygments --ignore-vuln CVE-2026-4539.
Pygments has been patched upstream; the ignore no longer matches
anything.
- Fix defusedxml import style in print_queue.py to be recognized by Bandit
(use `import defusedxml.ElementTree as ET` not `from defusedxml import`)
- Update Trivy scanner version from 0.65.0 to 0.69.1
