CVE-2026-84712 (GCVE-0-2026-84712)

Vulnerability from cvelistv5 – Published: 2026-09-23 19:40 – Updated: 2026-11-06 01:06

Title

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

Summary

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.

Severity

Exposure can be reduced by restricting network access to the automation-controller API so that only trusted networks and health probes can reach it: block or restrict external access to the /api/v2/ping/ and /api/controller/v2/ping/ routes at the reverse proxy, load balancer, or firewall, and front health checks with an infrastructure-level probe that does 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."

The\n                  unauthenticated health-check endpoint /api/v2/ping/\n                  (ApiV2PingView, AllowAny) over-serializes RBAC-gated\n                  automation-mesh data into its anonymous response, exposing the\n                  full instance inventory (node hostnames, node types, UUIDs,\n                  heartbeats, capacities, and exact versions), all instance-group\n                  names and membership, the deployment install UUID, and the\n                  active control node. A remote, unauthenticated attacker can use\n                  this to map the control plane and fingerprint software versions\n                  for targeted attacks. This flaw affects confidentiality only;\n                  it does not expose secrets, credentials, or tenant data.",

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
