Summary
Tilt defines dev environments as code for microservice apps on Kubernetes. From 0.19.5 through 0.37.3, the Tilt HUD server mounts Go net/http/pprof handlers under /debug with no access control. When the HUD or apiserver listener is network-exposed, an unauthenticated caller can read process memory through /debug/pprof/heap and /debug/pprof/goroutine, including session and apiserver tokens, and degrade performance through /debug/pprof/profile or /debug/pprof/trace. This issue is fixed in version 0.37.4.
