CVE-2018-1002102 is a low-severity vulnerability rated 2.6/10 on the CVSS scale. Improper validation of URL redirection in the Kubernetes API server in versions prior to v1.14.0 allows an attacker-controlled Kubelet to redirect API server requests from streaming endpoints to arbitrary hosts. Impacted API servers will follow the redirect as a GET request with client-certificate credentials for authenticating to the Kubelet.. EPSS estimates a 0.62% chance of exploitation in the next 30 days.
