Description
The Forms Rb plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.9. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to read form submission records, modify form configuration options, and delete records belonging to any form they do not own.
