Prior to 1.5.7 and 1.6.2, EnvoyExtensionPolicy Lua scripts executed by Envoy proxy can be used to leak the proxy's credentials. These credentials can then be used to communicate with the control plane and gain access to all secrets that are used by Envoy proxy, e.g. TLS private keys and credentials used for downstream and upstream communication. This vulnerability is fixed in 1.5.7 and 1.6.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-94"],"references":["https://github.com/envoyproxy/gateway/security/advisories/GHSA-xrwg-mqj6-6m22","https://access.redhat.com/security/cve/CVE-2026-22771","https://bugzilla.redhat.com/show_bug.cgi?id=2428735","https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-22771.json"],"products":["envoyproxy:gateway"],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2026-22771","score":0.00622,"percentile":0.49814,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-xrwg-mqj6-6m22","url":"https://osv.dev/vulnerability/GHSA-xrwg-mqj6-6m22","summary":"Envoy Extension Policy lua scripts injection causes arbitrary command execution","modified":"2026-09-10T03:50:59.323502450Z","packages":[{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","purl":"pkg:golang/github.com/envoyproxy/gateway","ranges":[">=1.6.0-rc.0 <1.6.2"],"fixed":["1.6.2"]},{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","purl":"pkg:golang/github.com/envoyproxy/gateway","ranges":["<1.5.7"],"fixed":["1.5.7"]}]},{"id":"GO-2026-4312","url":"https://osv.dev/vulnerability/GO-2026-4312","summary":"Envoy Extension Policy lua scripts injection causes arbitrary command execution in github.com/envoyproxy/gateway","modified":"2026-02-04T03:32:56.386930Z","packages":[{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","purl":"pkg:golang/github.com/envoyproxy/gateway","ranges":["<1.5.7",">=1.6.0-rc.0 <1.6.2"],"fixed":["1.5.7","1.6.2"]}]}],"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).
