The WP Media Category Management plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions 2.0 to 2.3.3. This is due to missing or incorrect nonce validation on the wp_mcm_handle_action_settings() function. This makes it possible for unauthenticated attackers to alter plugin settings, such as the taxonomy used for media, the base slug for media categories, and the default media category via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

There is functionality in the Store Locator Plus for WordPress plugin through 5.5.14 that made it possible for authenticated users to update their user meta data to become an administrator on any site using the plugin.
