Eventin permits custom-role users to include PHP files through event_layout

Eventin through 4.1.22 allows authenticated users with the custom-level access described by the advisory to supply event_layout values that include and execute existing server-side PHP files. The included code can expose sensitive data or bypass access controls. Executing attacker-supplied PHP requires an additional means of placing a suitable PHP file on the server.

Source record

Technical description

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.
