## Technical details

A vulnerability classified as Incorrect Default Permissions (CWE-276) exists in the OTRS External Interface and the ConfigItem List module. The flaw allows an authenticated customer user to bypass intended access restrictions and query the system for Configuration Item (CI) information from the CMDB. For a system to be vulnerable, the CMDB must be enabled and 'CustomerGroupSupport' must be active. The attack requires network access and low-level customer authentication, though the CVSS vector suggests some level of user interaction may be involved. The issue is addressed in OTRS version 2026.4.X.
