CVE-2026-16544 Details
Description
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.
A missing authorization flaw in AWX's websocket event consumer allows any authenticated user to subscribe to certain unmapped event groups and receive real-time stdout output from jobs in organizations they do not belong to. This vulnerability arises because the consumer_access() function only maps authorization checks for some event groups, leaving others unprotected. As a result, users can access sensitive job data across organizations, including potentially confidential information such as SCM credentials. This issue affects all versions of Ansible Automation Platform that include the Controller component.
Users are advised to restrict account creation to trusted individuals, use external authentication methods with strict group mappings, review and manage user accounts, monitor websocket subscriptions for unusual activity, avoid embedding credentials in certain configurations, and apply network segmentation to limit access to the AWX/Controller web interface.
