Name of the Vulnerable Software and Affected Versions Related Posts for WordPress plugin versions 2.0.4 and earlier

Description The issue allows high privilege users, such as admins, to set XSS payloads in the heading text and CSS settings due to a lack of sanitization, leading to Stored Cross-Site Scripting issues.

Recommendations For versions 2.0.4 and earlier, update to a version that addresses the sanitization issue in the heading text and CSS settings to prevent Stored Cross-Site Scripting. As a temporary workaround, consider restricting access to the settings that allow modification of heading text and CSS to minimize the risk of exploitation.
