What is CVE-2025-65033?

Rallly, a collaborative scheduling tool, exhibits an authorization flaw in its poll management feature, impacting user integrity and application availability. Before version 4.5.4, authenticated users could manipulate any poll by merely referencing the public pollId, without any constraints on ownership verification. This allowed unauthorized modifications, enabling disruptive actions on polls potentially leading to misinformation and operational inefficiencies. The vulnerability has been addressed in version 4.5.4.
