CVE-2023-33946Network attack vector

Cross-instance object disclosure via faulty OAuth scope isolation

Published May 24, 2023 · Updated Oct 22, 2024

Improper access control in Liferay Portal and DXP 7.4 allows remote authenticated users to view objects from another virtual instance. The Object module fails to isolate object visibility by virtual instance when the OAuth 2 scope administration page enumerates objects. A remote authenticated user with administration-page access in one virtual instance can read, but not modify, objects belonging to another instance.
