Summary
A flaw was found in hawtio-operator. 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.
Red Hat has determined that this vulnerability is Critical severity. The combination of a public OAuthClient with automatic grant approval and tenant-controlled redirect URIs enables OAuth token theft without user consent.
An attacker with edit access in any namespace can craft an authorization URL that redirects tokens to an attacker-controlled host. Red Hat recommends setting GrantMethod to prompt, adding ScopeRestrictions, and generating a client secret.
Red Hat severity: Important — CVSS 8.7 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N). Weakness: CWE-1390.
Affected Red Hat products: Red Hat build of Apache Camel - HawtIO 4. Red Hat does not currently list a fixing RHSA for this CVE.

Mitigation checklist
- Administrators can mitigate this issue by manually patching the OAuthClient resource created by the hawtio-operator to set grantMethod to 'prompt' instead of 'auto', and by adding a client secret. This forces explicit user consent for each OAuth authorization request and prevents unauthorized token acquisition. Monitor OpenShift OAuth server audit logs for unexpected authorization grants to the hawtio OAuthClient.
