Event deletion via missing nonce validation
Published Feb 14, 2026 · Updated Feb 14, 2026
Cross-site request forgery in sourcez SEATT: Simple Event Attendance 1.5.0 and earlier allows remote attackers to delete events. The event-deletion handler in seatt_events_admin.php accepts a deletion request without validating a WordPress nonce, so the administrator's active session authorizes the operation. Exploitation requires an administrator to visit a crafted link or page while authenticated; the demonstrated consequence is deletion of arbitrary event records.
