What the vulnerability does

01Description

The WP Learn Manager plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.8. 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 install and activate arbitrary plugins from the WordPress.org repository on the vulnerable site.
