Vulnerability Overview

The HTML Forms – Simple WordPress Forms Plugin for WordPress is vulnerable to Unauthenticated Stored Cross-Site Scripting in all versions up to and including 1.6.0 due to insufficient sanitization of fabricated file upload field metadata before displaying it in the WordPress admin dashboard. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute whenever an administrator accesses the form submissions page.

Technical Analysis

REMEDIATION: Update to version 1.6.1, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
