CVE-2026-93685

Unauthenticated operational data disclosure via exposed debug endpoint

Published Sep 18, 2026 · Updated Sep 18, 2026

Information exposure in Red Hat Advanced Cluster Management for Kubernetes allows remote attackers to read operational data without authentication. The addon-framework configuration created by cmdfactory.NewControllerCommandConfig leaves diagnostic handlers reachable on port 8443 after a basic TLS handshake. Adjacent-network access exposes goroutine, heap, and command-line details for reconnaissance but does not provide direct code execution.
