Advanced iFrame <= 2025.2 - Authenticated (Contributor+) Stored Cross-Site Scripting

EPSS Percentile
0th
The Advanced iFrame plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'advanced_iframe' shortcode in all versions up to, and including, 2025.2 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This was partially patched in version 2024.5, and later improved in version 2025.3.
