CVE-2026-55882 · Severity: high · CVSS 4 · Published 2026-07-10

Tilt, a tool used by developers to manage microservice environments on Kubernetes, contains a security flaw in its management interface (HUD server). If the interface is exposed to the network, unauthorized individuals can access sensitive internal diagnostic data, including security tokens and process memory. This could lead to the theft of credentials or a disruption of the development environment's performance.

## Technical details

The Tilt HUD server and apiserver listener mount Go 'net/http/pprof' handlers under the /debug path without any access control or authentication. When Tilt is configured to listen on a network-accessible interface (e.g., using --host 0.0.0.0), an unauthenticated remote attacker can access endpoints such as /debug/pprof/heap and /debug/pprof/goroutine to leak sensitive information, including session and apiserver tokens. Additionally, access to /debug/pprof/profile or /debug/pprof/trace can be used to consume CPU resources and degrade system performance. The fix in version 0.37.4 restricts these endpoints to loopback connections and implements CSRF protections.
