CVE-2026-44514

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.

Summary		(es) Kubetail es un panel de registro en tiempo real para Kubernetes. Antes de la 0.14.0, el panel de Kubetail exponía puntos finales de WebSocket que no validaban adecuadamente el encabezado Origin en la actualización de la conexión. Una página web maliciosa visitada por un usuario con una sesión de Kubetail activa podría abrir un WebSocket al panel del usuario y leer sus registros de Kubernetes en tiempo real. Esto es una vulnerabilidad de Cross-Site WebSocket Hijacking (CSWSH) y afecta tanto a la implementación de escritorio (por defecto http://localhost:7500) como a las implementaciones en clúster (típicamente detrás de un Ingress con autenticación básica HTTP). Esta vulnerabilidad se corrige en la 0.14.0.
