Scheduler Widget <= 0.1.6 - Insecure Direct Object Reference to Authenticated (Subscriber+) Arbitrary Event Modification
Published Feb 14, 2026

MEDIUMCVSS 3.1
EPSS 0.33%
Description
The Scheduler Widget plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 0.1.6. This is due to the `scheduler_widget_ajax_save_event()` function lacking proper authorization checks and ownership verification when updating events. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify any event in the scheduler via the `id` parameter granted they have knowledge of the event ID.
