Description

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 is due to the plugin not properly verifying that a user is authorized to perform an action. 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.
