CVE-2026-8690

The RentMy Real-Time Rental Management Plugin plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.0.4.1.

This makes it possible for unauthenticated attackers to read, create, update, and delete event records stored in the rentmy_events WordPress option, as well as overwrite the rentmy_locationId option.
