CVE-2025-65028

Rallly is an open-source scheduling and collaboration tool. Prior to version 4.5.4, an insecure direct object reference (IDOR) vulnerability allows any authenticated user to modify other participants’ votes in polls without authorization. The backend relies solely on the participantId parameter to identify which votes to update, without verifying ownership or poll permissions. This allows an attacker to alter poll results in their favor, directly compromising data integrity. This issue has been patched in version 4.5.4.

Summary		(es) Rallly es una herramienta de código abierto para la planificación y colaboración. Versiones anteriores a la versión 4.5.4, una vulnerabilidad de referencia directa a objeto insegura (IDOR) permite a cualquier usuario autenticado modificar los votos de otros participantes en encuestas sin autorización. El backend se basa únicamente en el parámetro 'participantId' para identificar qué votos actualizar, sin verificar la propiedad o los permisos de la encuesta. Esto permite a un atacante alterar los resultados de la encuesta a su favor, comprometiendo directamente la integridad de los datos. Este problema ha sido parcheado en la versión 4.5.4.
