Summary

The Automatic.css plugin for WordPress is vulnerable to Stored Cross-Site Scripting via REQUEST_URI in version 4.0.0 due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts that execute whenever an administrator accesses the Activity Log settings page.

Risk Assessment

The risk involves malicious script execution in the administrator's session context, potentially leading to data theft, session hijacking, or other unauthorized actions in the WordPress admin panel.

Recommendation
