CVE-2025-4581Network attack vector

Pre-authentication internal network access via unvalidated OpenSSO URLs

Published Aug 9, 2025 · Updated Aug 11, 2025

SSRF in Liferay Portal 7.4.0 through 7.4.3.132 allows remote attackers to make arbitrary HTTP requests to internal systems. Affected Liferay DXP releases share an OpenSSO settings component that accepts user-supplied URLs without proper validation and directs the server to request them. Exploitation requires no account but requires passive user interaction; blind requests enable internal network enumeration without returning the fetched response directly.
