+  "summary": "Woodpecker gRPC agent_id metadata can be spoofed- cross-tenant agent impersonation",
+  "details": "### Impact\nA 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.\n\n### Patches\nDirect patch: https://github.com/woodpecker-ci/woodpecker/pull/6567\nLater proper fix: https://github.com/woodpecker-ci/woodpecker/pull/6569\n\n### Workarounds\nDisable org agents (`WOODPECKER_DISABLE_USER_AGENT_REGISTRATION=true`) and delete existing ones\n\n### Resources\nPublic ref: https://github.com/woodpecker-ci/woodpecker/issues/6541\nPrivate com: https://github.com/woodpecker-ci/woodpecker-security/issues/21",
