Vulnerability Overview

The MonsterInsights plugin for WordPress is vulnerable to Stored Cross-Site Scripting via post titles and pages in versions up to, and including, 8.9.0 due to insufficient input sanitization and output escaping on those values. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page if they are able to successfully spoof a request to Google Analytics.

Technical Analysis

REMEDIATION: Update to version 8.9.1, 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.
