Vulnerability Overview

The WP Maintenance plugin for WordPress is vulnerable to Cross-Site Scripting in versions up to, and including, 6.0.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with administrative permissions and above to inject arbitrary web scripts that execute in a victim's browser. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Technical Analysis

REMEDIATION: Update to version 6.0.8, 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.
