What is CVE-2026-15667?

The Event Calendar, Event Registration, Tickets & Booking plugin for WordPress allows authenticated users with contributor-level access to exploit a Local File Inclusion (LFI) vulnerability through the 'event_layout' parameter. This issue affects all versions up to and including 4.1.22, potentially enabling attackers to include and execute arbitrary PHP files stored on the server. As the etn_manage_event capability is assigned to Contributors by default, they can manipulate the REST API to set malicious values for event_layout, leading to unauthorized access to sensitive data or even complete code execution if PHP files can be uploaded to the server.

Affected Version(s)

Eventin – Event Calendar, Tickets, Registration, Booking & WooCommerce 0 <= 4.1.22
