The Calculated Fields Form – AI Form Builder for WordPress – Contact, Payment, Quote, Quiz & More plugin for WordPress is vulnerable to Reflected DOM-Based Cross-Site Scripting via the 'arbitrary (whichever names the admin bound via url.<name>)' parameter in all versions up to, and including, 5.5.1.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Exploitation requires the targeted site to host a publicly accessible form in which an administrator has configured at least two fields with url.<name> predefined values that are used together in a concatenation equation — a plausible but not universal configuration.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
