Starting in version 3.0.0 and prior to version 3.14.1, a vulnerability in Woodpecker CI's gRPC layer allowed any authenticated agent to impersonate any other agent on the same server by injecting a forged `agent_id` value into outgoing gRPC metadata. The server correctly verified the JWT token but then discarded the verified agent identity in favor of the client-supplied value. Version 3.14.1 patches the issue. As a workaround, disable org agents (`WOODPECKER_DISABLE_USER_AGENT_REGISTRATION=true`) and delete existing ones.","state":0,"publishedAt":"2026-06-18T14:13:38.065+00:00","modifiedAt":"2026-06-18T16:10:41.914+00:00","affected":[{"ecosystem":"Vendor product","name":"woodpecker","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"woodpecker-ci\",\n                    \"product\": \"woodpecker\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 3.0.0, < 3.14.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.1,"severity":"HIGH"}],"references":["https://github.com/woodpecker-ci/woodpecker/security/advisories/GHSA-g7mm-9vx7-jm7h","https://github.com/woodpecker-ci/woodpecker-security/issues/21","https://github.com/woodpecker-ci/woodpecker/issues/6541","https://github.com/woodpecker-ci/woodpecker/pull/6567","https://github.com/woodpecker-ci/woodpecker/pull/6569"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-50141","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-50141","identifiers":["CVE-2026-50141"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
