CVE-2026-14450Network attack vector

Cross-tenant privilege escalation via forged identity headers

Published Aug 10, 2026 · Updated Aug 10, 2026

Authentication bypass in Red Hat OpenShift AI 3.4 allows remote authenticated users to gain cross-tenant privileges through forged headers. The MaaS API trusts X-MaaS-Username and X-MaaS-Group verbatim instead of authenticating requests independently of the Kuadrant AuthPolicy gateway. Control of any cluster pod is required; successful requests can mint ServiceAccount tokens in other namespaces, revoke API keys, and read model-access configuration.
