Executive Summary

The Simple JWT Login WordPress plugin before version 3.6.8 has a flaw where it does not check the audience of Google identity tokens during login. This allows unauthenticated users to create tokens with any email address, including admin emails, and gain unauthorized access to accounts.

Detection Guidance

Check the installed version of the Simple JWT Login plugin in your WordPress site. If it is below 3.6.8, the vulnerability is present. You can verify this via the WordPress admin panel under Plugins or by checking the plugin files directly.

Impact Analysis

This vulnerability allows attackers to take over any user account, including administrator accounts, by exploiting improper token validation. This could lead to full site compromise, data theft, or unauthorized actions on the WordPress site.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive user data, violating GDPR and HIPAA requirements for data protection and access control. Non-compliance may result in legal penalties and reputational damage.

Mitigation Strategies

Update the Simple JWT Login plugin to version 3.6.8 or later immediately. Disable Google sign-in functionality if not required until the update is applied. Review user accounts for any unauthorized access and reset passwords for all users, especially administrators.
