fix(ci): build releases with the toolchain pinned in go.mod - #50
Conversation
setup-go exports GOTOOLCHAIN=local, so the go.mod toolchain directive was inert and the 1.26.x wildcard resolved to the go1.26.5 already sitting in the runner tool cache. goreleaser compiled v2.0.0 with 1.26.5 while go.mod pinned go1.26.6, and the release Dockerfile only repacks that tarball, so the published image shipped eight HIGH stdlib CVEs. GOTOOLCHAIN=auto restores the pin on the release build and on the PR checks, so what is tested and what is shipped agree. Also bumps golang.org/x/text to v0.41.0 for CVE-2026-56852. MVS pulls the rest of the golang.org/x family along with it. Fixes: #49 Signed-off-by: Alexander Chernov <alexander@chernov.it>
A daily Trivy sweep plus a govulncheck reachability pass, reporting through a single deduplicated tracking issue that is rewritten in place when the finding set changes and closes itself once a scan comes back clean. The published image is scanned separately from main because main can be clean while a released tag rots, which is precisely what #49 was: go.mod pinned go1.26.6 and the shipped binary was still built with 1.26.5, so a main-only scan would have stayed green throughout. Findings are triaged by a report job that cannot run on partial data, so a failed scan can never close the tracking issue by reporting a clean result it never established.

If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughThe pull request adds scheduled and manual vulnerability scanning for Go binaries and container images. It aggregates findings into a GitHub tracking issue, adds Bash regression tests, aligns CI toolchain selection, and upgrades indirect Go modules. ChangesSecurity scanning and CVE reporting
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change updates release toolchain selection and adds automated vulnerability reporting, but it can still build with a different Go version than intended and can overwrite or close the wrong tracking issue under certain scan runs. The PR is not merge-ready until those bounded workflow and reporting risks are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

… digest workflow_dispatch runs on any branch the caller picks, and the report job would then rewrite or close the shared tracking issue from a branch scan. A feature branch that happened to be clean could close an issue tracking real findings on main, which is the same false-clean failure the missing `if: always()` already guards against. Gate the job on the default branch. The issue lookup matched on the cve-scan label alone, so a human labelling an unrelated issue would see it silently overwritten or closed. Match on the digest marker this script writes instead, and refuse when more than one tracking issue matches rather than guessing. Refs: #49 Signed-off-by: Alexander Chernov <alexander@chernov.it>
The docker ecosystem was missing entirely, so a CVE in the golang: builder or the distroless runtime base was invisible to Dependabot and only surfaced in the image scan added by #50. golang.org/x/* is now grouped because minimal version selection pulls the whole family in behind any one member; #50 moved seven of them to bump x/text alone, so ungrouped bumps arrive as several PRs editing the same go.mod lines. The actions are grouped for a different reason: they are independent of each other, but a bump apiece costs a full CI run each. Every group is declared twice, once per applies-to. Groups default to version-updates, so security updates would otherwise arrive ungrouped once they are switched on. Signed-off-by: Alexander Chernov <alexander@chernov.it>

go.mod has pinned
toolchain go1.26.6since #40, but setup-go exportsGOTOOLCHAIN=local, which makes that directive inert, so the1.26.xwildcard resolved to the go1.26.5 already in the runner tool cache and goreleaser built v2.0.0 with it.GOTOOLCHAIN=autorestores the pin. golang.org/x/text goes to v0.41.0 for the ninth finding.The second commit adds a daily Trivy scan of main and, separately, of the published image, since main can be clean while a released tag rots, which is what happened here. Findings go to one tracking issue that closes itself once a scan comes back clean.
Note this fixes how releases are built, not the image already out there: :latest stays vulnerable until a tag is cut.
