Prior to 1.33.1, 1.32.4, 1.31.6, and 1.30.10, Envoy's ext_proc HTTP filter is at risk of crashing if a local reply is sent to the external server due to the filter's life time issue. A known situation is the failure of a websocket handshake will trigger a local reply leading to the crash of Envoy. This vulnerability is fixed in 1.33.1, 1.32.4, 1.31.6, and 1.30.10.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-460"],"references":["https://github.com/envoyproxy/envoy/commit/8eda1b8ef5ba8663d16a737ab99458c039a9b53c","https://github.com/envoyproxy/envoy/security/advisories/GHSA-cf3q-gqg7-3fm9","https://github.com/envoyproxy/envoy/security/advisories/GHSA-cf3q-gqg7-3fm9"],"products":["envoyproxy:envoy"],"source":"nvd","synced_at":"2026-10-19T22:00:28.034033815+00:00"},"epss":{"cve":"CVE-2025-30157","score":0.00436,"percentile":0.37904,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cf3q-gqg7-3fm9","url":"https://osv.dev/vulnerability/GHSA-cf3q-gqg7-3fm9","summary":"Envoy crashes when HTTP ext_proc processes local replies","modified":"2026-09-10T03:49:48.463519140Z","packages":[{"ecosystem":"Go","name":"github.com/envoyproxy/envoy","purl":"pkg:golang/github.com/envoyproxy/envoy","ranges":["<1.30.10"],"fixed":["1.30.10"]},{"ecosystem":"Go","name":"github.com/envoyproxy/envoy","purl":"pkg:golang/github.com/envoyproxy/envoy","ranges":[">=1.31.0 <1.31.6"],"fixed":["1.31.6"]},{"ecosystem":"Go","name":"github.com/envoyproxy/envoy","purl":"pkg:golang/github.com/envoyproxy/envoy","ranges":[">=1.32.0 <1.32.4"],"fixed":["1.32.4"]},{"ecosystem":"Go","name":"github.com/envoyproxy/envoy","purl":"pkg:golang/github.com/envoyproxy/envoy","ranges":[">=1.33.0 <1.33.1"],"fixed":["1.33.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
