The CVE-2025-XXXX vulnerability exists within the `expandoTableLocalService` component of Liferay Portal. This service is responsible for managing custom expandable database tables. The flaw is an improper access control mechanism that fails to adequately enforce permission checks on specific service methods. An authenticated remote attacker can exploit this weakness by crafting a malicious HTTP request that calls a vulnerable method within the service. This request bypasses the intended authorization layers, allowing the attacker to perform unauthorized actions. These actions could include unauthorized reading of data from or writing of data to custom Expando tables, potentially leading to a confidentiality and integrity impact within the application’s custom data structures.
