{"cve":"CVE-2025-25294","nvd":{"published":"2025-03-06T19:15:27.267","modified":"2026-06-17T09:00:38.020","status":"Analyzed","description":"Envoy Gateway is an open source project for managing Envoy Proxy as a standalone or Kubernetes-based application gateway. In all Envoy Gateway versions prior to 1.2.7 and 1.3.1 a default Envoy Proxy access log configuration is used. This format is vulnerable to log injection attacks. If the attacker uses a specially crafted user-agent which performs json injection, then he could add and overwrite fields to the access log. This vulnerability is fixed in 1.3.1 and 1.2.7. One can overwrite the old text based default format with JSON formatter by modifying the \"EnvoyProxy.spec.telemetry.accessLog\" setting.","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:L/A:N","score":5.3},"cwes":["CWE-117"],"references":["https://github.com/envoyproxy/gateway/commit/8f48f5199cf1bbb9a8ac0695c5171bfef6c9198a","https://github.com/envoyproxy/gateway/security/advisories/GHSA-mf24-chxh-hmvj"],"products":["envoyproxy:gateway"],"source":"nvd","synced_at":"2026-10-19T22:00:17.429720821+00:00"},"epss":{"cve":"CVE-2025-25294","score":0.00286,"percentile":0.21165,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-mf24-chxh-hmvj","url":"https://osv.dev/vulnerability/GHSA-mf24-chxh-hmvj","summary":"Envoy Gateway Log Injection Vulnerability","modified":"2026-09-10T03:50:56.848559841Z","packages":[{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","purl":"pkg:golang/github.com/envoyproxy/gateway","ranges":["<1.2.7"],"fixed":["1.2.7"]},{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","purl":"pkg:golang/github.com/envoyproxy/gateway","ranges":[">=1.3.0-rc.1 <1.3.1"],"fixed":["1.3.1"]}]},{"id":"GO-2025-3504","url":"https://osv.dev/vulnerability/GO-2025-3504","summary":"Envoy Gateway Log Injection Vulnerability in github.com/envoyproxy/gateway","modified":"2026-02-04T04:32:08.838752Z","packages":[{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","purl":"pkg:golang/github.com/envoyproxy/gateway","ranges":["<1.2.7",">=1.3.0-rc.1 <1.3.1"],"fixed":["1.2.7","1.3.1"]}]}],"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).
