What is CVE-2025-65032?

Rallly, an open-source scheduling and collaboration tool, harbors an Insecure Direct Object Reference (IDOR) vulnerability that impacts user data integrity. Prior to version 4.5.4, any authenticated user could exploit this vulnerability to alter the display names of other participants in polls without possessing administrative privileges or being the poll owner. This exploitation occurs by manipulating the 'participantId' parameter in name modification requests, leading to potential impersonation attacks and confusion amongst users. The issue has since been remediated in version 4.5.4, ensuring a more robust security posture.
