CVE-2026-11821 PUBLISHED

Eventin <= 4.1.17 - Missing Authorization to Authenticated (Subscriber+) Notification Flow Management via notification-flow REST API Endpoint

Assigner: Wordfence
Reserved: 09.06.2026 Published: 09.09.2026 Updated: 09.09.2026

The Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.1.17. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to view, create, update, clone, and delete notification flow event automation workflows that should be restricted to administrators.
