{"id":"CVE-2025-30157","summary":"Envoy crashes when HTTP ext_proc processes local replies","details":"Envoy is a cloud-native high-performance edge/middle/service proxy. 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.","aliases":["BIT-envoy-2025-30157","GHSA-cf3q-gqg7-3fm9"],"modified":"2026-08-12T15:16:23.624854Z","published":"2025-03-21T14:49:18.113Z","related":["openSUSE-SU-2025:14938-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-460"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/30xxx/CVE-2025-30157.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/30xxx/CVE-2025-30157.json"},{"type":"ADVISORY","url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-cf3q-gqg7-3fm9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-30157"},{"type":"FIX","url":"https://github.com/envoyproxy/envoy/commit/8eda1b8ef5ba8663d16a737ab99458c039a9b53c"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/envoyproxy/envoy","events":[{"introduced":"0"},{"fixed":"9adc6873ea3abc2305d164af41ea713bb45152dd"},{"introduced":"7b8baff1758f0a584dcc3cb657b5032000bcb3d7"},{"fixed":"8b0d0de9e7d601989121cbb42efc170c342f55c3"},{"introduced":"86dc7ef91ca15fb4957a74bd599397413fc26a24"},{"fixed":"cb67308e01e8f035f2977f153d20d99a54cb1da4"},{"introduced":"b0f43d67aa25c1b03c97186a200cc187f4c22db3"},{"fixed":"8eda1b8ef5ba8663d16a737ab99458c039a9b53c"}],"database_specific":{"cpe":["cpe:2.3:a:envoyproxy:envoy:*:*:*:*:*:*:*:*","cpe:2.3:a:envoyproxy:envoy:1.33.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"0"},{"fixed":"1.30.10"},{"introduced":"1.31.0"},{"fixed":"1.31.6"},{"introduced":"1.32.0"},{"fixed":"1.32.4"},{"introduced":"1.33.0"},{"last_affected":"1.33.0"}],"source":["CPE_RANGE","CPE_STRING","REFERENCES"]}}],"versions":["1.33.0","v1.33.0","v1.31.5","v1.32.3","v1.30.9","v1.32.2","v1.31.4","v1.30.8","v1.31.3","v1.32.1","v1.30.7","v1.32.0","v1.31.2","v1.30.6","v1.30.5","v1.31.1","v1.31.0","v1.30.4","v1.30.3","v1.30.2","v1.30.1","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-2025-30157.json","vanir_signatures_modified":"2026-08-12T15:16:23Z","vanir_signatures":[{"deprecated":false,"digest":{"threshold":0.9,"line_hashes":["131107222101786345073671344768637688516","219310465844859572002083520237094622140","266204614104953369355689299540733038565"]},"id":"CVE-2025-30157-0ab17785","signature_type":"Line","signature_version":"v1","source":"https://github.com/envoyproxy/envoy/commit/8eda1b8ef5ba8663d16a737ab99458c039a9b53c","target":{"file":"source/extensions/filters/http/ext_proc/ext_proc.h"}},{"signature_version":"v1","source":"https://github.com/envoyproxy/envoy/commit/8eda1b8ef5ba8663d16a737ab99458c039a9b53c","target":{"file":"test/extensions/filters/http/ext_proc/ext_proc_misc_test.cc"},"deprecated":false,"digest":{"line_hashes":["104788104435975027144784111992021314565","126602166397583842061410150030390187922","328477059728527897037608437804609887847","131204744563129597769789680942071510244","244873183816677666353347552793792954197","60274442199458527312234911024310920421","120395095692324732441389757229971149318","19990929774941915240165922035079353089","5625019625493324857300223908946513159","110973575682060680996234595202656074400","65750863178146682149261283764239191807","19133073729328977944058538349737305800","235883629140950495644257161399368874396","262673547002466384584703133528529055882"],"threshold":0.9},"id":"CVE-2025-30157-3426cb99","signature_type":"Line"},{"id":"CVE-2025-30157-f33dc8df","signature_type":"Line","signature_version":"v1","source":"https://github.com/envoyproxy/envoy/commit/8eda1b8ef5ba8663d16a737ab99458c039a9b53c","target":{"file":"source/common/router/router.h"},"deprecated":false,"digest":{"line_hashes":["79712408649916740326025507022540481296","25495714045157038637322642769908678571","52058331756079616835538700678553070843","322318600054933349052125588450060845213","166519388076965811213541388181571030716","330040150232917346293243912962234022276","246995351906158912600667086697741049429","162351276269284561165518139247861000969"],"threshold":0.9}},{"deprecated":false,"digest":{"line_hashes":["30194948638454257386779764387151425144","167798196906891989626433148408180070218","249084642809662306428799710429784003743","168382228229502581714931651007745254179","112324955763538154936775478766254269775","171680254834255452050177127767755846953","327674794315972961491357729946898061004"],"threshold":0.9},"id":"CVE-2025-30157-fafd4579","signature_type":"Line","signature_version":"v1","source":"https://github.com/envoyproxy/envoy/commit/8eda1b8ef5ba8663d16a737ab99458c039a9b53c","target":{"file":"source/common/runtime/runtime_features.cc"}}]}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"C
