{"id":"CVE-2026-50572","summary":"Envoy: ext_authz - RawHttpClientImpl onSuccess 0x0 segfault","details":"Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1, Envoy's HTTP external-authorization client can retain a stale request callback after a request is rejected. When RawHttpClientImpl::onSuccess later processes the authorization response, it can invoke callbacks_ after the callback owner has been destroyed, causing a use-after-free and process crash under production traffic. The relevant scope boundary is that the vulnerable path uses the HTTP ext_authz client; the advisory does not establish the same trigger for unrelated filters. This issue is fixed in versions 1.36.10, 1.37.6, 1.38.4, and 1.39.1.","aliases":["GHSA-q8wp-gf7q-m8cv"],"modified":"2026-09-24T03:45:25.773116719Z","published":"2026-09-21T19:32:00.008Z","related":["openSUSE-SU-2026:11630-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-416"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50572.json"},"references":[{"type":"WEB","url":"https://github.com/envoyproxy/envoy/releases/tag/v1.36.10"},{"type":"WEB","url":"https://github.com/envoyproxy/envoy/releases/tag/v1.37.6"},{"type":"WEB","url":"https://github.com/envoyproxy/envoy/releases/tag/v1.38.4"},{"type":"WEB","url":"https://github.com/envoyproxy/envoy/releases/tag/v1.39.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50572.json"},{"type":"ADVISORY","url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-q8wp-gf7q-m8cv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50572"},{"type":"FIX","url":"https://github.com/envoyproxy/envoy/commit/8dacef38337aeffd62866b5c5910104b63b33db8"},{"type":"FIX","url":"https://github.com/envoyproxy/envoy/commit/a49085623654e27e9ad6298928557644b849d7ce"},{"type":"FIX","url":"https://github.com/envoyproxy/envoy/commit/c1b29534a294cb0999e99e1fe0de000310165f03"},{"type":"FIX","url":"https://github.com/envoyproxy/envoy/commit/c524571ffad517ba650d9563f85afa89194e2cfb"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/envoyproxy/envoy","events":[{"introduced":"0"},{"introduced":"6d9bb7d9a85d616b220d1f8fe67b61f82bbdb8d3"},{"introduced":"f1dd21b16c244bda00edfb5ffce577e12d0d2ec2"},{"introduced":"8eea3285d6bdb89f8ea34632cfe7ce1608a8f374"},{"fixed":"053a8989382dd91542ecf0cef8f379b9cb761cdd"},{"fixed":"cf413bdb37b36d3ffbe570b8a48760abe2b588f5"},{"fixed":"ef2d997c1b022cf8b849a1d3521fbf234d79ca26"},{"fixed":"b579d07d3ad7ee11d32b105e91a5a39ad24718d7"},{"fixed":"8dacef38337aeffd62866b5c5910104b63b33db8"},{"fixed":"a49085623654e27e9ad6298928557644b849d7ce"},{"fixed":"c1b29534a294cb0999e99e1fe0de000310165f03"},{"fixed":"c524571ffad517ba650d9563f85afa89194e2cfb"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.36.10"},{"introduced":"1.37.0"},{"fixed":"1.37.6"},{"introduced":"1.38.0"},{"fixed":"1.38.4"},{"introduced":"1.39.0"},{"fixed":"1.39.1"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.39.0","v1.36.9","v1.38.3","v1.37.5","v1.38.2","v1.37.4","v1.36.8","v1.38.1","v1.37.3","v1.36.7","v1.38.0","v1.37.2","v1.36.6","v1.37.1","v1.36.5","v1.37.0","v1.36.4","v1.36.3","v1.36.2","v1.36.1","v1.36.0","v1.35.0","v1.34.0","v1.33.0","v1.32.0","v1.31.0","v1.30.0","v1.29.0","v1.28.0","v1.27.0","v1.26.0","v1.25.0","v1.24.0","v1.23.0","v1.22.0","v1.21.0","v1.20.0","v1.19.0","v1.18.2","v1.18.1","v1.18.0","v1.17.0","v1.16.0","v1.15.0","v1.14.0","v1.13.0","v1.12.0","v1.11.0","v1.10.0","v1.9.0","v1.8.0","v1.7.0","v1.6.0","v1.5.0","v1.4.0","v1.3.0","v1.2.0","v1.1.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-50572.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
