The websocket RBAC mechanism was introduced as part of the fix for CVE-2020-10698, but the consumer_access() function was never updated to cover all subscribable event groups. Exploitation requires a valid authenticated user account on the AWX/Controller instance, but no specific role or organization membership is needed. The attacker receives stdout and event metadata in real time for inventory updates, project updates, and system jobs across all organizations. In multi-tenant deployments (including managed services), this allows one tenant's users to observe another tenant's job output.", "threat_severity": "Moderate"}
