Vulnerability Overview

The WP Courses LMS plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions before 2.0.44 due to improper handling of the unfiltered_html capability. This makes it possible for administrator-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

REMEDIATION: Update to version 2.0.44, 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.
