Prior to versions 1.26.0, 1.25.3, 1.24.4, 1.23.6, and 1.22.9, the OAuth filter assumes that a `state` query param is present on any response that looks like an OAuth redirect response. Sending it a request with the URI path equivalent to the redirect path, without the `state` parameter, will lead to abnormal termination of Envoy process. Versions 1.26.0, 1.25.3, 1.24.4, 1.23.6, and 1.22.9 contain a patch. The issue can also be mitigated by locking down OAuth traffic, disabling the filter, or by filtering traffic before it reaches the OAuth filter (e.g. via a lua script). \n"}],"source":{"advisory":"GHSA-j79q-2g66-2xv5","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T12:16:35.397Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-j79q-2g66-2xv5","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-j79q-2g66-2xv5"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-02-10T21:34:11.044829Z","id":"CVE-2023-27496","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-02-10T21:34:14.824Z"}}]}}
