AI-suggested
Until an official fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the 'additional' parameter in the Advanced iFrame plugin. Monitor vendor channels for updates and apply patches promptly once released.
Description
The Advanced iFrame plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'additional' parameter in version less than, or equal to, 2025.6 due to insufficient input sanitization and output escaping. 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.
