What the vulnerability does

01Description

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.

Explanation of Vulnerability in Simple Terms

02Summary

Academy LMS versions up to 3.5.0 contain a critical vulnerability that allows unauthenticated attackers to read sensitive data, modify site content, or disrupt service without any user interaction. The vulnerability stems from improper access control that fails to restrict unauthorized requests. All sites running this plugin should update immediately.
