The Tutor LMS Pro plugin for WordPress versions up to 3.9.5 contains a critical authentication bypass vulnerability in its Social Login addon. The flaw occurs because the plugin fails to verify that the email provided in authentication requests matches the email from validated OAuth tokens. This allows unauthenticated attackers to log in as any existing user, including administrators, by combining a valid OAuth token from their own account with a victim's email address. The vulnerability affects all versions up to and including 3.9.5 and poses a significant security risk to WordPress sites using this plugin.
