Vulnerability Overview

The Gutenverse Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG file upload in all versions up to, and including, 2.3.2. This is due to the plugin's framework component adding SVG to the allowed MIME types via the upload_mimes filter without implementing any sanitization of SVG file contents. This makes it possible for authenticated attackers, with Author-level access and above, to upload SVG files containing malicious JavaScript that executes when the file is viewed, leading to arbitrary JavaScript execution in victims' browsers.

Technical Analysis

REMEDIATION: Update to version 2.4.0, 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.
