Description

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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • mdempfle Advanced iFrame — Up to and including 2025.2
  • tinywebgallery advanced_iframe — Before 2025.3
