CVE-2026-1987
No known patch is available for this vulnerability.
The affected plugin has been removed from the WordPress.org directory (reason: Security Issue), and no patched version is being distributed through the official directory. If you have the affected software installed, you should uninstall or replace it rather than wait for an update.
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.
