AI-suggested
There is no configuration option to reduce the data returned by the unauthenticated /api/v2/ping/ endpoint. Operators should restrict network access to the automation-controller API so that only trusted networks and health probes can reach it. This includes blocking or restricting external access to the /api/v2/ping/ and /api/controller/v2/ping/ routes at the reverse proxy, load balancer, or firewall. Health checks should be fronted with infrastructure-level probes that do not proxy the /ping/ endpoint to untrusted clients. The definitive fix is to update to a version of automation-controller that no longer serializes instance, instance-group, install UUID, and active-node data in the unauthenticated response.
Description
CVE-2026-84712 is a vulnerability in Red Hat Ansible Automation Platform 2.5 for RHEL 8 where the unauthenticated health-check endpoint /api/v2/ping/ over-serializes sensitive automation-mesh data. This exposure allows remote attackers to obtain detailed instance inventory and deployment information, potentially aiding targeted attacks. The flaw affects confidentiality but does not expose secrets, credentials, or tenant data. There is no configuration workaround to trim the data returned by this endpoint. Operators should restrict network access to the API and front health checks with infrastructure probes that do not proxy the /ping/ endpoint. The definitive fix is to update to a version that stops serializing sensitive data in the unauthenticated response.
