The daily container scan reported 211 license policy violations for
ghcr.io/github/gh-aw-firewall/agent:0.28.1. Reproducing the scan locally against the pinned digest with the repo's pinned scanner (anchore/grant:v0.6.8) shows 182 denied packages, all of them Ubuntu 22.04 base-imagedebpackages (GPL/LGPL/Artistic/"no license found" families). No application-level dependency violates the policy.Changes
.grant.yaml: added the 182 Ubuntu 22.04 base OS packages toignore-packagesunder a labelled section, matching the existing precedent for Alpine base OS, the Debian base OS ofghcr.io/github/github-mcp-server, and the Node/npm runtime. Header comment updated to name the Ubuntu-based agent image. The allowlist still applies to every other package in the image.After the change the image evaluates as
compliant(denied: 0,ignored: 213) instead ofnoncompliant(denied: 182).Not addressed here
The 5 High vulnerabilities (
ip-address10.2.0 → 10.3.1,brace-expansion5.0.7 → 5.0.9, Go stdlib go1.26.5) are baked into the upstream agent image and must be fixed ingithub/gh-aw-firewall:v0.28.1is already the newest AWF release, so there is noDefaultFirewallVersionbump available..grype.yamlignore rule would be inappropriate — that file is reserved for findings with no upstream fix, and all five have one.
