CVE-2026-58658Public exploitNetwork attack vector

Unauthenticated log disclosure via unguarded worker routers

Published Jul 15, 2026 · Updated Jul 15, 2026

Missing authentication in GPUStack 2.2.1 and earlier allows remote attackers to read inference logs and alter worker logging over the network. The worker HTTP server mounts the /serveLogs and /debug routers without worker_request_auth, so requests can enumerate model IDs, stream prompts and completions, change log levels, and read memory profiles. Reachability to the worker port, which binds to all interfaces by default, is sufficient; no account or user interaction is required.
