The websocket event consumer performs RBAC authorization checks only for event groups that are mapped in the consumer_access() function (job_events, workflow_events, ad_hoc_command_events). Three event groups - inventory_update_events, project_update_events, and system_job_events — are not mapped, causing the authorization check to be skipped. Any authenticated user can subscribe to these unmapped websocket event groups for any object ID and receive real-time stdout output from jobs belonging to organizations they have no access to.

Since any authenticated user can exploit this flaw regardless of role, minimizing the number of user accounts reduces the attack surface.\n- Use external authentication (LDAP, SAML, OIDC) with strict group mappings to prevent self-registration and ensure only authorized users can log in.\n- Review the list of AWX/Controller users and remove or deactivate any accounts that are no longer needed.\n- Monitor websocket connections and subscriptions for unusual patterns, such as a user subscribing to inventory_update_events or project_update_events for object IDs outside their organization.\n- Avoid embedding credentials in SCM URLs or inventory source configurations, as these may appear in stdout output. Use credential objects instead.\n- Apply network segmentation to restrict access to the AWX/Controller web interface to trusted networks only."}],"timeline":[{"lang":"en","time":"2026-07-22T09:56:58.086Z","value":"Reported to Red Hat."},{"lang":"en","time":"2026-07-22T00:00:00.000Z","value":"Made public."}],"credits":[{"lang":"en","value":"Red Hat would like to thank Ta Duc Thien (Ninh Thanh Security team (NTCS)) for reporting this issue."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-07-22T11:15:53.882Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-22T17:47:34.263602Z","id":"CVE-2026-16544","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-22T17:47:45.889Z"}}]}}
