CVE-2026-84712— Automation-controller: automation-controller: unauthenticated /api/v2/ping/ discloses automation-mesh instance topology and instance-group membership

Quick assessment

Affected
Red Hat Red Hat Ansible Automation Platform 2.5 for RHEL 8
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 automation-controller API 中发现了一个漏洞。未经验证的健康检查端点 （ApiV2PingView, AllowAny）在其匿名响应中过度序列化了受 RBAC 控制的自动化网格数据，导致完整实例清单（节点主机名、节点类型、UUID、心跳、容量和确切版本）、所有实例组名称及成员关系、部署安装 UUID 以及活动控制节点被暴露。远程未授权攻击者可利用此漏洞绘制控制平面拓扑，并识别软件版本以实施定向攻击。该漏洞仅影响机密性，不暴露密钥、凭证或租户数据。

Vulnerability Title
Automation-controller: automation-controller: unauthenticated /api/v2/ping/ discloses automation-mesh instance topology and instance-group membership
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the automation-controller API. The unauthenticated health-check endpoint /api/v2/ping/ (ApiV2PingView, AllowAny) over-serializes RBAC-gated automation-mesh data into its anonymous response, exposing the full instance inventory (node hostnames, node types, UUIDs, heartbeats, capacities, and exact versions), all instance-group names and membership, the deployment install UUID, and the active control node. A remote, unauthenticated attacker can use this to map the control plane and fingerprint software versions for targeted attacks. This flaw affects confidentiality only; it does not expose secrets, credentials, or tenant data.
