CVE-2026-12801CVE-2026-12801

Description

The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Range Slider 'data-label' and 'data-separator' attributes in all versions up to, and including, 3.5.43 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.
