## Affected

- wpmudev Forminator Forms – Contact Form, Payment Form & Custom Form Builder: through 1.44.1

## Description

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘id' and 'data-size’ parameters in all versions up to, and including, 1.44.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
