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.

Affected WordPress components

  • Form Maker by 10Web – Mobile-Friendly Drag & Drop Contact Form Builder Plugin · form-maker
    Confirmed match Active
    Up to and including 1.15.40
    View on WordPress.org

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions
