No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 7.3.7.4 via the em_options_save function. This makes it possible for authenticated attackers, with administrator-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. The stored traversal key is subsequently executed via an include_once() call that fires on every admin_init invocation — including unauthenticated admin-ajax.php requests — meaning once the malicious key is stored by an administrator, the inclusion is triggered without any further authentication or capability check.
