Summary

The Live CSS Preview plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'wp_ajax_frontend_save' AJAX endpoint in all versions up to, and including, 2.1.4. This makes it possible for authenticated attackers with Subscriber-level access and above to update the plugin's CSS setting.

Risk Assessment

A low-privileged attacker can change the plugin's CSS settings, potentially altering the site's appearance or enabling further attacks. This compromises the integrity of the plugin configuration.

Recommendation

Update the Live CSS Preview plugin to a version later than 2.1.4. Until then, consider restricting access to the AJAX endpoint or disabling the plugin.
