{"cve":"CVE-2026-50141","nvd":{"published":"2026-06-18T14:17:29.400","modified":"2026-10-25T23:10:00.167","status":"Deferred","description":"Woodpecker is a CI/CD engine. 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.","cvss_v4":{"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},"cvss_v3":null,"cwes":["CWE-290","CWE-639"],"references":["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","https://github.com/woodpecker-ci/woodpecker/security/advisories/GHSA-g7mm-9vx7-jm7h"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-50141","score":0.00427,"percentile":0.36716,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-g7mm-9vx7-jm7h","url":"https://osv.dev/vulnerability/GHSA-g7mm-9vx7-jm7h","summary":"Woodpecker gRPC agent_id metadata can be spoofed- cross-tenant agent impersonation","modified":"2026-07-21T19:19:07.139675684Z","packages":[{"ecosystem":"Go","name":"go.woodpecker-ci.org/woodpecker/v3","purl":"pkg:golang/go.woodpecker-ci.org/woodpecker/v3","ranges":[">=3.0.0 <3.14.1"],"fixed":["3.14.1"]}]},{"id":"GO-2026-5976","url":"https://osv.dev/vulnerability/GO-2026-5976","summary":"Woodpecker gRPC agent_id metadata can be spoofed- cross-tenant agent impersonation in go.woodpecker-ci.org/woodpecker","modified":"2026-07-21T19:15:30.601330649Z","packages":[{"ecosystem":"Go","name":"go.woodpecker-ci.org/woodpecker","purl":"pkg:golang/go.woodpecker-ci.org/woodpecker","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"go.woodpecker-ci.org/woodpecker/v2","purl":"pkg:golang/go.woodpecker-ci.org/woodpecker/v2","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"go.woodpecker-ci.org/woodpecker/v3","purl":"pkg:golang/go.woodpecker-ci.org/woodpecker/v3","ranges":[">=3.0.0 <3.14.1"],"fixed":["3.14.1"]}]}],"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).
