Vulnerability Title
Form Maker by 10Web <= 1.15.40 - Unauthenticated Stored Cross-Site Scripting via Matrix Field Text Box
Source: NVD (National Vulnerability Database)
Vulnerability Description
The Form Maker by 10Web plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Matrix field (Text Box input type) in form submissions in all versions up to, and including, 1.15.40. This is due to insufficient input sanitization (`sanitize_text_field` strips tags but not quotes) and missing output escaping when rendering submission data in the admin Submissions view. This makes it possible for unauthenticated attackers to inject arbitrary JavaScript through a form submission that executes in the browser of an administrator who views the submission details.
