CVE-2025-43827Network attack vector

Cross-instance audit-event disclosure via unchecked company ownership

Published Sep 30, 2025 · Updated Sep 30, 2025

Authorization bypass in affected Liferay Portal and Liferay DXP releases allows remote authenticated users to view another instance's audit events. AuditPortlet fetches the auditEventId-selected event without comparing its company ID with the current permission checker's company ID. A company administrator in one virtual instance can therefore read another instance's audit records; integrity and availability are unaffected.
