Authenticated event modification via unchecked identifier
Published Feb 14, 2026 · Updated Feb 14, 2026
Insecure direct object reference in Scheduler Widget 0.1.6 and earlier allows remote authenticated users to modify arbitrary events. The scheduler_widget_ajax_save_event function accepts an attacker-controlled id parameter and updates the selected event without authorization or ownership checks. Subscriber-level access and knowledge of an event ID are sufficient; the documented consequence is unauthorized event modification.
