Name of the Vulnerable Software and Affected Versions Kubernetes versions prior to 1.15.0 Kubernetes versions prior to 1.14.4 Kubernetes versions prior to 1.13.8 Kubernetes versions prior to 1.12.10

Description The issue concerns the exposure of the debugging endpoint "/debug/pprof" over the unauthenticated Kubelet healthz port. This can potentially leak sensitive information, such as internal Kubelet memory addresses and configuration, or cause limited denial of service. The go pprof endpoint is also exposed over the Kubelet's healthz port.

Recommendations For versions prior to 1.15.0, update to version 1.15.0 or later. For versions prior to 1.14.4, update to version 1.14.4 or later. For versions prior to 1.13.8, update to version 1.13.8 or later. For versions prior to 1.12.10, update to version 1.12.10 or later. As a temporary workaround, consider restricting access to the "/debug/pprof" endpoint to minimize the risk of exploitation.
