CVE-2025-65031

Rallly is an open-source scheduling and collaboration tool. Prior to version 4.5.4, an improper authorization flaw in the comment creation endpoint allows authenticated users to impersonate any other user by altering the authorName field in the API request. This enables attackers to post comments under arbitrary usernames, including privileged ones such as administrators, potentially misleading other users and enabling phishing or social engineering attacks. This issue has been patched in version 4.5.4.

Summary		(es) Rallly es una herramienta de código abierto para programación y colaboración. Versiones anteriores a la versión 4.5.4, una falla de autorización impropia en el endpoint de creación de comentarios permite a usuarios autenticados suplantar a cualquier otro usuario alterando el campo authorName en la solicitud de la API. Esto permite a los atacantes publicar comentarios bajo nombres de usuario arbitrarios, incluyendo aquellos privilegiados como los administradores, lo que podría engañar a otros usuarios y facilitar ataques de phishing o ingeniería social. Este problema ha sido parcheado en la versión 4.5.4.
