This vulnerability allows any pod within the cluster to bypass the Kuadrant AuthPolicy gateway by forging HTTP headers, specifically `X-MaaS-Username` and `X-MaaS-Group`, which are trusted verbatim. This lack of first-party authentication enables an attacker to gain unauthorized access and escalate privileges. The concrete consequences include the ability to mint Kubernetes ServiceAccount tokens in other tenants' namespaces, revoke API keys, and exfiltrate sensitive model access configuration."}],"affected":[{"vendor":"Red Hat","product":"Red Hat OpenShift AI 3.4","collectionURL":"https://catalog.redhat.com/software/containers/","packageName":"rhoai/odh-maas-api-rhel9","defaultStatus":"affected","versions":[{"version":"1785850409","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:openshift_ai:3.4::el9"]},{"vendor":"Red Hat","product":"Red Hat OpenShift AI (RHOAI)","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"rhoai/odh-maas-controller-rhel9","defaultStatus":"unaffected","cpes":["cpe:/a:redhat:openshift_ai"]},{"vendor":"Red Hat","product":"Red Hat OpenShift AI (RHOAI)","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"rhoai/odh-mod-arch-maas-rhel9","defaultStatus":"unaffected","cpes":["cpe:/a:redhat:openshift_ai"]}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:53262","name":"RHSA-2026:53262","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/security/cve/CVE-2026-14450","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2496373","name":"RHBZ#2496373","tags":["issue-tracking","x_refsource_REDHAT"]}],"datePublic":"2026-08-10T18:42:25.268Z","problemTypes":[{"descriptions":[{"cweId":"CWE-290","description":"Authentication Bypass by Spoofing","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-290: Authentication Bypass by Spoofing","timeline":[{"lang":"en","time":"2026-07-02T07:18:50.042Z","value":"Reported to Red Hat."},{"lang":"en","time":"2026-08-10T18:42:25.268Z","value":"Made public."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-08-11T18:38:35.680Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-11T17:44:30.745621Z","id":"CVE-2026-14450","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-11T17:51:52.059Z"}}]}}
