{"id":"GHSA-m2v6-2jmh-4c68","summary":"Envoy Gateway: Nil-dereference when SecurityPolicy targets TCPRoute without spec.authorization","details":"Vulnerability report without repro case. Repro case may be added later after harness is complete.\n\n**Preconditions (4):**\n- Tenant has SecurityPolicy + TCPRoute RBAC (baseline)\n- Tenant namespace permitted to attach TCPRoute to a Gateway listener\n- spec.authorization omitted (the trigger)\n- No admission webhook blocks the shape\n\n**Description:**\n\nA namespace-scoped tenant can deterministically panic the gatewayapi runner on every reconcile with a single CRD; the recover() in message/watchutil.go:53 keeps the process alive but unwinds the entire handle() callback in runner/runner.go:192, so xDS/Infra IR publishing stalls controller-wide until an admin deletes the object. Data plane keeps serving last-good config.","aliases":["BIT-envoy-gateway-2026-53719","CVE-2026-53719","GO-2026-6009"],"modified":"2026-09-21T09:40:50.641771053Z","published":"2026-07-16T19:19:17Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-476"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-07-16T19:19:17Z"},"references":[{"type":"WEB","url":"https://github.com/envoyproxy/gateway/security/advisories/GHSA-m2v6-2jmh-4c68"},{"type":"PACKAGE","url":"https://github.com/envoyproxy/gateway"}],"affected":[{"package":{"name":"github.com/envoyproxy/gateway","ecosystem":"Go","purl":"pkg:golang/github.com/envoyproxy/gateway"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.8.0-rc.0"},{"fixed":"1.8.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-m2v6-2jmh-4c68/GHSA-m2v6-2jmh-4c68.json"}},{"package":{"name":"github.com/envoyproxy/gateway","ecosystem":"Go","purl":"pkg:golang/github.com/envoyproxy/gateway"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.7.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-m2v6-2jmh-4c68/GHSA-m2v6-2jmh-4c68.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
