CVE-2025-65028

Rallly Has an IDOR Vulnerability in Vote Update Endpoint Allows Unauthorized Manipulation of Participant Votes

Published Nov 19, 2025 CVSS 3.1 · 6.5 Medium EPSS < 1% KEV · Not listed
Description
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.
