{"id":"CVE-2026-53719","aliases":["GO-2026-6009"],"url":"https://o3.security/vulnerability/CVE-2026-53719","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.","published":"2026-07-16T19:19:17Z","modified":"2026-09-10T03:50:52.551198058Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","fixedVersion":"1.8.1"},{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","fixedVersion":"1.7.4"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/envoyproxy/gateway/security/advisories/GHSA-m2v6-2jmh-4c68"},{"type":"PACKAGE","url":"https://github.com/envoyproxy/gateway"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:50:52.551198058Z"}}
