This CVE involves a reflected XSS vulnerability in Liferay Portal (versions 7.4.0 to 7.4.3.132) and Liferay DXP (multiple affected versions). An authenticated attacker can inject malicious JavaScript into message board threads and categories by crafting a specially crafted request. When other users view the manipulated content, the script executes in their browser context, potentially leading to session hijacking, data theft, or unauthorized actions. The vulnerability arises due to insufficient input sanitization in thread/category handling.
