  "title": "SAML response validation bypass in gpustack",
  "summary": "gpustack versions 0.7.1 through versions before 2.2.2 do not properly validate SAML responses at the SAML callback. An unauthenticated network client that can reach this endpoint may obtain a session as an existing user, including an administrator, or cause a new user to be created; SAML does not need to be enabled for exposure.",
  "mitigation": "Upgrade gpustack to version 2.2.2 or later. Until upgrade is complete, block network access to /auth/saml/callback at the ingress, reverse proxy, or equivalent network control.",
