CVE-2025-43790Network attack vector

Cross-instance data access and modification via unchecked identifiers

Published Sep 11, 2025 · Updated Sep 11, 2025

IDOR in Liferay Portal and Liferay DXP allows remote authenticated users to access or alter objects across virtual instances. Object entry and definition operations accept caller-controlled identifiers without enforcing that the referenced object belongs to the caller's virtual instance. An account in one virtual instance is required; affected releases are Portal 7.4.0 through 7.4.3.124 and DXP 2024.Q1.1 through 2024.Q1.12, 2024.Q2.0 through 2024.Q2.6, and 7.4 GA through update 92.
