Key facts

Description

The Academy LMS – WordPress LMS Plugin for Complete eLearning Solution plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 3.5.0. This is due to the plugin not properly validating a user's identity prior to updating their password and relying solely on a publicly-exposed nonce for authorization. This makes it possible for unauthenticated attackers to change arbitrary user's password, including administrators, and gain access to their account.
