CVE-2025-65021

Rallly is an open-source scheduling and collaboration tool. Prior to version 4.5.4, an Insecure Direct Object Reference (IDOR) vulnerability exists in the poll finalization feature of the application. Any authenticated user can finalize a poll they do not own by manipulating the pollId parameter in the request. This allows unauthorized users to finalize other users’ polls and convert them into events without proper authorization checks, potentially disrupting user workflows and causing data integrity and availability issues. 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 vulnerabilidad de Referencia Directa Insegura a Objeto (IDOR) existe en la característica de finalización de encuestas de la aplicación. Cualquier usuario autenticado puede finalizar una encuesta que no le pertenece manipulando el parámetro pollId en la solicitud. Esto permite a usuarios no autorizados finalizar encuestas de otros usuarios y convertirlas en eventos sin las comprobaciones de autorización adecuadas, interrumpiendo potencialmente los flujos de trabajo de los usuarios y causando problemas de integridad y disponibilidad de los datos. Este problema ha sido parcheado en la versión 4.5.4.
