The frontend image was flagged on nginx 1.31.0 because the Dockerfiles used the floating nginx:alpine (mainline) tag. No rewrite directives exist in any nginx config, so the named-capture mitigation does not apply; the remediation is the version update. Pin every nginx reference to the patched 1.31.1-alpine release: - frontend/Dockerfile, Dockerfile.production, Dockerfile.simple - deployment/local-test/14-nginx-proxy.yaml (was nginx:alpine) - deployment/local-test/l7-sample-apps.yaml (was nginx:1.25-alpine) Validated with `nginx -t` on 1.31.1 for all configs.
