CVE-2024-6703: Fluentforms Contact Form

Medium severity, CVSS 5.4. EPSS: 0.3% chance of exploitation in the next 30 days.

The Contact Form Plugin by Fluent Forms for Quiz, Survey, and Drag & Drop WP Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘description’ and 'btn_txt' parameters in all versions up to, and including, 5.1.19 due to insufficient input sanitization and output escaping. This makes it possible for attackers with the Form Manager permissions and Subscriber+ user role, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Affected products

• Fluentforms Contact Form: before 5.1.20 (fixed in 5.1.20)
