Tutor LMS Pro Authentication Bypass Vulnerability in WordPress

An authentication bypass vulnerability has been identified in the Tutor LMS Pro plugin for WordPress, affecting all versions up to and including 3.9.5. The issue arises in the Social Login addon, where the plugin fails to verify that the email provided in the authentication request matches the email associated with the validated OAuth token. This flaw allows unauthenticated attackers to log in as any existing user, including administrators, by using a valid OAuth token from their own account along with the victim's email address.

Impact

Exploitation of this vulnerability allows for unauthorized login as any user, including those with administrative privileges.
