The CVE-2025-XXXXX vulnerability is a missing authorization flaw within the Collection Provider component of Liferay Portal and DXP. This component is responsible for managing content collections, often linked to Blueprints for content structure. The vulnerability exists because the application does not properly verify a user’s permissions when handling requests to this provider. Specifically, it fails to check if an authenticated user, operating within one portal instance, is authorized to access data from a different instance. This allows a user with basic instance-level access to craft a request that reads and selects Blueprints from other, separate instances. The flaw stems from insufficient access control checks on the server-side endpoints for the Collection Provider, permitting cross-instance data leakage without the proper tenant or instance-level authorization.
