Prior to 2.2.0, get_current_user in gpustack/api/auth.py treated a loopback request source as the built-in administrator when force_auth_localhost was false, which was the default. A remote request could appear to originate from 127.0.0.1 because client_ip_getter accepted a same-host reverse proxy peer or a client-supplied X-GPUStack-Real-IP loopback value. The bypass allowed unauthenticated administrative access, including user and model changes, persistent administrator API-key creation, disclosure of worker and cloud-provider secrets, and code execution through POST /v2/inference-backends/from-yaml. Exploitation was observed in the wild against a 2.1.1 deployment. This issue is fixed in version 2.2.0."}], "lastModified": "2026-11-09T19:42:09.450", "cisaActionDue": "2026-11-12", "cisaExploitAdd": "2026-11-09", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:gpustack:gpustack:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "3439BFF0-7E02-4EFF-B772-F42FFB05A582", "versionEndExcluding": "2.2.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com", "cisaRequiredAction": "Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA\u2019s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA\u2019s \u201cForensics Triage Requirements\u201d (see URL in Notes).
