## Technical details

An improper access control vulnerability (CWE-306) exists in the API documentation endpoint of Devolutions PowerShell Universal versions 2026.1.7 and earlier. The flaw allows a remote, unauthenticated attacker to retrieve the OpenAPI specification for user-defined REST endpoints. This occurs because the application fails to enforce authentication requirements on the documentation endpoint. By accessing this specification, an attacker can gain detailed knowledge of available API routes, expected parameters, and data structures, which facilitates reconnaissance for further exploitation. The issue is resolved in PowerShell Universal version 2026.2.0.
