Name of the Vulnerable Software and Affected Versions Advanced iFrame plugin for WordPress versions up to, and including, 2023.8

Description The issue is related to Stored Cross-Site Scripting via the 'advanced iframe' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 2023.8, update to a version later than 2023.8 to resolve the issue. As a temporary workaround, consider restricting access to the 'advanced iframe' shortcode for users with contributor-level and above permissions until a patch is available.
