Kubetail: Cross-Site WebSocket Hijacking allows attacker to read Kubernetes logs from authenticated users

Kubetail is a real-time logging dashboard for Kubernetes. Prior to 0.14.0, Kubetail's dashboard exposes WebSocket endpoints that did not adequately validate the Origin header on connection upgrade. A malicious web page visited by a user with an active Kubetail session could open a WebSocket to the user's dashboard and read their Kubernetes logs in real time. This is a Cross-Site WebSocket Hijacking (CSWSH) vulnerability and affects both the desktop deployment (default http://localhost:7500) and cluster deployments (typically behind an Ingress with HTTP basic auth). This vulnerability is fixed in 0.14.0.
