Executive Summary

This vulnerability in the Academy LMS WordPress plugin allows an unauthenticated attacker to escalate privileges by taking over user accounts. It occurs because the plugin does not properly validate a user's identity before allowing a password update and relies only on a publicly-exposed nonce for authorization. As a result, attackers can change the password of any user, including administrators, and gain access to their accounts.

Mitigation Strategies

Immediate mitigation steps include updating the Academy LMS WordPress plugin to a version later than 3.5.0 where the vulnerability is fixed. Until an update is available, restrict access to the plugin and monitor for unauthorized password changes, especially for administrator accounts. Avoid relying on the plugin's nonce-based authorization as it is publicly exposed and insufficient. Consider disabling the plugin temporarily if possible to prevent exploitation.

Compliance Impact

The vulnerability allows unauthenticated attackers to escalate privileges by taking over accounts, including administrators, through password changes without proper identity validation. This unauthorized access can lead to exposure or manipulation of sensitive user data, potentially violating data protection regulations such as GDPR and HIPAA that require strict access controls and protection of personal information. Therefore, this vulnerability negatively impacts compliance with these standards by undermining user authentication and data security.
