Conversation
The pinned traefik image (v3.3, released Dec 2024) is on an unmaintained minor branch. Current upstream security fixes only land on v3.7.x/v3.6.x/v2.11.x. Notably CVE-2026-33186 (gRPC-Go HTTP/2 :path pseudo-header authorization bypass, CVSS 7.8) was fixed in v3.6.12/v3.7.0-ea.3 and is not backported to v3.3. Bumping to the v3.7 floating tag keeps the container on a supported, patched branch. Also bumps the traefik feature's own devcontainer-feature.json version (1.3.1 -> 1.3.2) per this repo's semver convention for tool version bumps.

Summary
Automated dependency/version audit of the pinned CLI/tool versions across
src/*/devcontainer-feature.jsonandinstall.sh, plus the top-levelDockerfile.Most features (
bun,claude-code,gemini-cli,openai-codex,opencode,stripe-cli,supabase-cli,tinybird-cli) install from a "latest" channel (curl installer,npm install -gwithout a version pin,apt-get install, or a GitHubreleases/latestURL) and are not actually pinned to a stale version — nothing to bump there. TheDockerfilebase image (mcr.microsoft.com/devcontainers/base:bookworm) is a floating codename tag, also not pinned to a specific stale version.The one feature with a genuinely pinned, stale version is traefik:

v3.3is several minor versions behind the currently maintained branches (v2.11.x,v3.6.x,v3.7.xas of July 2026). Traefik has shipped multiple CVEs against v3.x since v3.3 was pinned, including::pathpseudo-header authorization bypass (CVSS 7.8, High). Fixed inv3.6.12/v3.7.0-ea.3.
