Medium severity, CVSS 5.4. EPSS: 0.4% chance of exploitation in the next 30 days.

The iframe forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'iframe' shortcode in versions up to, and including, 1.0 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.
