What is CVE-2026-16544?

A vulnerability in AWX has been identified where the websocket event consumer's Role-Based Access Control (RBAC) authorization checks are only applied to certain event groups, leaving others unprotected. Specifically, event groups such as inventory_update_events, project_update_events, and system_job_events are not included in the consumer_access() function, allowing any authenticated user to subscribe to these unmapped event groups. This oversight leads to potential unauthorized monitoring of real-time job stdout outputs from organizations that the user does not have access to, representing an incomplete remediation of a previous issue.
