When deploying Hawtio in cluster mode, the operator creates a cluster-scoped OAuthClient with automatic grant approval (GrantMethod: auto) and no client secret (public client). The redirect URIs are derived from the operator-created Route, whose hostname is tenant-controlled via the Hawtio CR spec.routeHostName field. A malicious tenant can register an arbitrary hostname as a valid OAuth redirect target and, because grants are auto-approved, obtain OpenShift access tokens of any cluster user who visits the crafted authorization URL without any consent prompt.","published":"2026-09-08T12:16:59.700","modified":"2026-09-08T12:16:59.700","cvss":{"score":8.7,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-80219"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2524895"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-08T12:16:59.700"}}
