Summary
The Advanced iFrame plugin for WordPress suffers from a vulnerability that allows authenticated users with contributor-level permissions and above to inject malicious scripts. This occurs via the 'advanced_iframe' shortcode, where inadequate input sanitization and output escaping of user-supplied attributes lead to potential exploitation.
