DescriptionThe Calculated Fields Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the form page href parameter in all versions up to, and including, 5.1.56 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. Exploitation requires the professional version or higher.
