AI-suggested
Upgrade GPUStack to version 2.2.0 or later, which addresses this authentication bypass vulnerability. Until upgrading, do not rely on the 'X-Gpustack-Real-IP' header for authentication or access control decisions. Implement network-level controls to restrict access to GPUStack management interfaces to trusted sources. Patch status is confirmed by the release of version 2.2.0.
Description
CVE-2026-102895 is an authentication bypass vulnerability in GPUStack, an open-source software managing GPU clusters for AI workloads. The flaw arises because GPUStack trusts the 'X-Gpustack-Real-IP' header to identify request origin. If this header indicates a loopback IP (127.0.0.1), GPUStack bypasses authentication, allowing attackers to spoof this header and gain unauthorized access. This affects all versions prior to 2.2.0, which was released at the end of June 2026. The vulnerability was publicly disclosed at the end of July 2026, with the CVE assigned on November 4, 2026. Exploit attempts have been observed but no confirmed exploitation in the wild is reported.
