Summary

The Optimize More! – CSS plugin for WordPress is vulnerable to Cross-Site Request Forgery (CSRF) in all versions up to, and including, 1.0.3. This is due to missing or incorrect nonce validation on the reset_plugin function. Unauthenticated attackers can reset the plugin's optimization settings via a forged request if they trick a site administrator into clicking a link.

Risk Assessment

Attackers can revert optimization settings to default, potentially degrading site performance. This can lead to slower page loads and negatively impact user experience.

Recommendation

Update the Optimize More! – CSS plugin to a version later than 1.0.3 if available, or consider removing it. Implement CSRF protections and regularly monitor performance settings.
