Prior to 8.1.6, ActorFollowModel.updateScore() interpolates the attacker-controlled ActivityPub actor inboxUrl into an SQL query, allowing an unauthenticated remote server to read and write PeerTube database tables, including oAuthToken.accessToken, and take over administrator accounts. This issue is fixed in version 8.1.6."

Antes de la versión 8.1.6, ActorFollowModel.updateScore() interpola la inboxUrl del actor de ActivityPub controlada por el atacante en una consulta SQL, permitiendo que un servidor remoto no autenticado lea y escriba tablas de la base de datos de PeerTube, incluyendo oAuthToken.accessToken, y tome el control de cuentas de administrador. Este problema se solucionó en la versión 8.1.6."
