Vulnerability Title
Tilt: Cross-site WebSocket hijacking of the Tilt HUD stream
Source: NVD (National Vulnerability Database)
Vulnerability Description
Tilt defines dev environments as code for microservice apps on Kubernetes. From 0.24.0 through 0.37.3, the Tilt HUD WebSocket at /ws/view is gated by a CSRF token, but the token is served by the unauthenticated /api/websocket_token endpoint and the upgrader accepts clients that omit an Origin header. When the HUD is network-exposed, an attacker who can reach the listener can open the HUD WebSocket and receive the full view stream, including session state, Tiltfile contents, resource statuses, and continued updates. This issue is fixed in version 0.37.4.
