CVE-2026-4388
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.
