Details

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Radio Field (Save and Continue Draft) in all versions up to, and including, 1.57.0.2 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. This is exploitable because the Save-and-Continue draft submission AJAX endpoint is registered as nopriv, allowing unauthenticated attackers to bypass radio field option-membership validation and persist a crafted payload that, when rendered on the Submissions admin page, is auto-executed via the bundled Inputmask library's data-attribute callback binding.

Severity
7.2 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N
