The CVE-2025-45424 vulnerability is a Cross-Site Request Forgery (CSRF) flaw within the Headless API of Liferay Portal. The vulnerability exists because the affected endpoints do not adequately validate the source of requests. A specific attack vector involves the manipulation of the ‘endpoint’ parameter. An attacker can craft a malicious webpage that, when visited by an authenticated Liferay user, silently submits a forged HTTP request to the vulnerable Liferay instance. This request leverages the ‘endpoint’ parameter to target and execute any Headless API action, effectively performing actions with the privileges of the unsuspecting victim. This allows for unauthorized creation, modification, or deletion of content and data within the portal.
