Justification

Vulnerable code not in execute path

Impact

github.com/sigstore/rekor@v1.3.6 is a transitive dependency vendored via the sigstore/cosign chain. The vulnerability is a decompression bomb in rekor's server-side Alpine APK log-entry parsing (/api/v1/log/entries). reports-server does not run a rekor server and never invokes these endpoints. govulncheck binary-mode analysis of the shipped reports-server binary confirms no rekor symbols are reachable (dead-code-eliminated). The vulnerable code path is never executed.
