      "value": "Tilt defines dev environments as code for microservice apps on Kubernetes. From 0.20.8 through 0.37.3, the Tilt HUD HTTP server registers handlers on a gorilla/mux router with no authenticating middleware. When the HUD is bound to a non-loopback address, an unauthenticated network caller can trigger developer-defined resources, tamper with Tiltfile arguments, read full engine state including the session token, and invoke apiserver resources through the token-attaching /proxy handler. This issue is fixed in version 0.37.4."

Desde la versión 0.20.8 hasta la 0.37.3, el servidor HTTP del HUD de Tilt registra gestores en un router gorilla/mux sin middleware de autenticación. Cuando el HUD está enlazado a una dirección que no es de loopback, un llamador de red no autenticado puede activar recursos definidos por el desarrollador, manipular los argumentos de Tiltfile, leer el estado completo del motor incluyendo el token de sesión, e invocar recursos del apiserver a través del gestor /proxy que adjunta el token. Este problema está solucionado en la versión 0.37.4."
