Content Staging <= 2.0.1 Authenticated Stored Cross-Site Scripting

Published Oct 21, 2021 · Updated Feb 14, 2025 · Assigned by Wordfence

Description

The Content Staging WordPress plugin is vulnerable to Stored Cross-Site Scripting due to insufficient input validation and escaping via several parameters that are echo'd out via the ~/templates/settings.php file which allowed attackers with administrative user access to inject arbitrary web scripts, in versions up to and including 2.0.1. This affects multi-site installations where unfiltered_html is disabled for administrators, and sites where unfiltered_html is disabled.
