Vulnerability in Eventin – Event Calendar, Tickets, Registration, Booking & WooCommerce — CVE-2026-15406

What to do now

Update Eventin – Event Calendar, Tickets, Registration, Booking & WooCommerce to 4.1.23 or later.

Affected versions

• Everything up to and including 4.1.22

The Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 4.1.22 via the 'event_layout' parameter parameter. This makes it possible for authenticated attackers, with custom-level access and above, to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included.
