A flaw was found in AWX. 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. This is an incomplete remediation of CVE-2020-10698.
