How the Mentioned CVE Works
The vulnerability CVE-2025-43790 is an Insecure Direct Object Reference (IDOR) flaw in Liferay Portal and DXP. It occurs because the application’s access control logic fails to properly verify a user’s permissions across different virtual instances. A virtual instance in Liferay is a fully isolated environment with its own data, users, and sites. The system inadequately validates object references, such as entry or definition IDs, when requests are made. An authenticated user in one virtual instance can manipulate object identifiers in API calls or web requests. By crafting a request with the ID of an object entry or definition from a different virtual instance, the user can bypass intended security boundaries. This allows the attacker to perform actions like viewing, editing, creating, or establishing relationships with data objects that belong to another tenant. The exploitation does not require high privileges; standard authenticated access is sufficient. The core failure is that the authorization check validates the user’s right to perform an action but does not confirm that the target object belongs to the user’s current virtual instance.
