      "value": "Woodpecker before 3.15.0 matches the ApprovalAllowedUsers bypass list against pipeline.Author. For the GitLab forge driver, pipeline.Author is populated from the git commit author name (commit.author.name) carried in the webhook payload, which is attacker-controlled and not verified by GitLab. A user who can open a merge request from a fork can set the commit author name to match an entry in ApprovalAllowedUsers, causing needsApproval to return false so the pipeline runs without the required approval. This defeats the fork-approval security boundary and allows execution of attacker-controlled pipeline steps on a Woodpecker agent and exfiltration of CI secrets exposed to the run. Other built-in forge drivers (Gitea, Forgejo, GitHub, Bitbucket) derive pipeline.Author from the forge-validated sender/actor identity and are not affected."

      "value": "Woodpecker anterior a la versión 3.15.0 compara la lista de omisión ApprovalAllowedUsers con pipeline.Author. Para el controlador de forja de GitLab, pipeline.Author se rellena a partir del nombre del autor del commit de git (commit.author.name) transportado en la carga útil del webhook, que es controlado por el atacante y no es verificado por GitLab. Un usuario que puede abrir una solicitud de fusión desde un fork puede establecer el nombre del autor del commit para que coincida con una entrada en ApprovalAllowedUsers, haciendo que needsApproval devuelva falso para que la pipeline se ejecute sin la aprobación requerida. Esto anula el límite de seguridad de aprobación de forks y permite la ejecución de pasos de pipeline controlados por el atacante en un agente de Woodpecker y la exfiltración de secretos de CI expuestos a la ejecución. Otros controladores de forja integrados (Gitea, Forgejo, GitHub, Bitbucket) derivan pipeline.Author de la identidad del remitente/actor validada por la forja y no se ven afectados."
