CVE-2026-93685

Summary

A flaw was found in the multicluster-observability-addon. A remote attacker can access a debug endpoint without authentication, due to a misconfiguration in the underlying addon-framework library. This allows for the disclosure of sensitive operational information, such as goroutine, heap, and command-line details, after completing a basic encrypted connection. This vulnerability does not enable direct remote code execution.

  • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Workarounds

To mitigate this issue, restrict network access to the pods running the multicluster-observability-addon to only trusted internal components. Implement network policies within your Kubernetes environment to limit inbound connections to the affected pods on ports 6060 and 8443 from untrusted sources. This operational control reduces the attack surface by preventing unauthorized access to the unauthenticated debug endpoints.
