CVE-2024-3053: Incsub Forminator

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

The Forminator – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘id’ forminator_form shortcode attribute in versions up to, and including, 1.29.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Affected products

• Incsub Forminator: before 1.29.3 (fixed in 1.29.3)
