The CVE-2025-12345 vulnerability is a stored Cross-site Scripting (XSS) flaw within Liferay Portal’s object management system. It specifically targets objects that utilize a rich text type field. The vulnerability arises from insufficient input sanitization and output encoding of user-supplied data within these fields. An attacker can craft a malicious payload containing JavaScript and inject it as the content of the rich text field. When this object is saved and subsequently viewed by another user, the embedded script is rendered and executed by the victim’s browser within the security context of the Liferay Portal site. This allows the attacker to perform actions on behalf of the victim, such as session hijacking, defacement, or redirecting the user to a malicious site, by exploiting the trust the application has in the retrieved content from its own database.
