The CVE-2025-XXXX vulnerability in Liferay Portal stems from improper neutralization of user-supplied input before its output in web pages. The flaw exists within the ‘Rich Text’ field type provided by the Data Engine module. This field fails to adequately sanitize crafted HTML and script payloads input by an attacker. When the stored content containing the malicious payload is subsequently rendered by the portal for other users, the embedded scripts execute within the victim’s browser context. The attack vector is network-based and requires the attacker to have permissions to create or edit content in specific modules such as Web Content Structures, Documents and Media Document Types, or custom assets utilizing the vulnerable field. This allows for theft of session cookies, defacement, or client-side request forgery.
