Description
The Kali Forms — Contact Form & Drag-and-Drop Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'digitalSignature' Field Value in all versions up to, and including, 2.4.18 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The required form-submission nonce is publicly available on any page containing the form shortcode, making this exploitable by fully unauthenticated attackers without any precondition beyond the form being published.
