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.
Direct patch: https://github.com/woodpecker-ci/woodpecker/pull/6567 Later proper fix: https://github.com/woodpecker-ci/woodpecker/pull/6569
Disable org agents (WOODPECKER_DISABLE_USER_AGENT_REGISTRATION=true) and delete existing ones
