Vulnerability Overview

The Patreon WordPress plugin for WordPress is vulnerable to Cross-Site Scripting in versions up to, and including, 1.8.1 due to insufficient privilege handling. This makes it possible for high-privilege users attackers to inject arbitrary web scripts that execute in a victim's browser even when the unfiltered_html capability is disallowed.

Technical Analysis

REMEDIATION: Update to version 1.8.2, 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.
