Advanced iFrame < 2024.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode

Description The Advanced iFrame plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2024.2 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.
