## What is CVE-2025-1439?

CVE-2025-1439 is a medium-severity cross-site scripting vulnerability in mdempfle Advanced iFrame, published on 26 Mar 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official 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, 2024.5 due to insufficient input sanitization and output escaping on user supplied attributes through the 'src' attribute when the src supplied returns a header with an injected value . 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.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)
