CVE-2025-43863

vantage6 is an open source framework built to enable, manage and deploy privacy enhancing technologies like Federated Learning and Multi-Party Computation. If attacker gets access to an authenticated session, they can try to brute-force the user password by using the change password functionality: they can call that route infinitely which will return the message that password is wrong until it is correct. This vulnerability is fixed in 4.11.

Summary		(es) vantage6 es un framework de código abierto diseñado para habilitar, administrar e implementar tecnologías que mejoran la privacidad, como el aprendizaje federado y la computación multipartita. Si un atacante accede a una sesión autenticada, puede intentar forzar la contraseña del usuario mediante la función de cambio de contraseña: puede llamar a esa ruta infinitamente, lo que devolverá el mensaje de que la contraseña es incorrecta hasta que sea correcta. Esta vulnerabilidad se corrigió en la versión 4.11.
