## Overview

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.
