Why: gitea 1.27.1 fixed CVE-2026-60004 + CVE-2026-59774 (both CVSS 9.8). The
2026-08-03 report printed gitea's CVE count as '1', the 2026-08-07 report as
'none'. Cause chain: the upgrade subagent read the GitHub release notes, which
name NEITHER cve (they are announced only in the vendor blog's security section),
so it recorded one unrelated minor item; the report then derived security content
from those notes plus model knowledge, and the model's training predates the CVEs.
Nothing in the pipeline ever queried an advisory source.
cc-ci-plan/advisory-scan.py — deterministic, per recipe, per upgrade window:
1. GitHub Security Advisories API for every source repo in the upstream registry.
PRIMARY: CVE + GHSA + severity + vulnerable/patched ranges, so 'fixed by THIS
upgrade' is computed. Needs no new per-recipe config (134 registry URLs are
already github.com).
2. Vendor release/security pages — every registry URL, fetched + regex-scanned.
This is the source that actually had the gitea CVEs.
3. OSV where a package mapping exists — supplementary.
Each source reports its own status so 'checked, none found' is never confused with
'not checked'. Source selection was measured, not assumed: for these two CVEs OSV
404'd and NVD's API had them by neither CPE, id, nor keyword — advisory DBs lag the
vendor, hence 1+2 lead.
Wiring is strictly ADDITIVE:
- /recipe-upgrade gains step 2a: run the scan, paste the block into the per-recipe
log, and report the UNION of it and the existing release-note reading. The scan
may never lower a count established by reading.
- /recipe-report treats the block as a FURTHER source, prefers its advisory ids /
severities / fixed-in versions for citation, and must render '?' (not 'none')
when a scan is absent or has failed sources — the false-clean 'none' is exactly
what happened on 2026-08-07.
- upstream/gitea.md records blog.gitea.com as the security-announcement URL.
Verified on the real regression: 1.27.0 -> 1.27.1 now yields exactly the 2 missed
criticals with their GHSA ids; the wider 1.26.2 -> 1.27.1 window yields 62.
