What is CVE-2025-65029?

Rallly, the open-source scheduling and collaboration tool, has an insecure direct object reference issue that impacts versions prior to 4.5.4. This vulnerability allows any authenticated user to delete arbitrary participants from polls without verifying ownership, posing a risk to data integrity and availability. By simply using a participant ID, an attacker can eliminate other users, including poll owners, from polls. This loophole undermines the reliability of poll participation data, affecting users' collaborative efforts. Users are advised to upgrade to version 4.5.4 or later to secure their accounts.
