CVE-2026-84712: Red Hat Ansible Automation Controller API information disclosure

CVE-2026-84712 · Severity: medium · CVSS 5.3 · Published 2026-09-23

Red Hat Ansible Automation Controller is a platform for managing infrastructure automation across enterprises. An unauthenticated attacker can access a public health-check endpoint that leaks sensitive internal infrastructure details including node names, deployment topology, versions, and identifiers. This exposes the control plane structure and enables fingerprinting for targeted attacks against the automation infrastructure.

Technologies: Red Hat Ansible Automation Platform. Vendors: Red Hat.

Technical details

The /api/v2/ping/ endpoint in Ansible Automation Controller over-serializes RBAC-protected automation-mesh data in its unauthenticated response, disclosing full instance inventory (hostnames, node types, UUIDs, heartbeats, capacities, versions), instance-group names and membership, deployment install UUID, and active control node information. No authentication is required; the attack is a simple HTTP GET. The vulnerability exposes confidential infrastructure topology but not secrets or credentials.
