Technical details
This vulnerability is an authentication bypass in GoLand's profiler component. The pprof (Go profiling) server injected by the profiler fails to enforce authentication, exposing profiling endpoints to unauthenticated network clients. The attack vector is network-based, requiring only network reachability to the profiler's listening port; no user interaction or prior authentication is needed. An attacker can retrieve CPU profiles, memory dumps, goroutine stacks, and other runtime metrics, potentially revealing application logic, data structures, and system resource usage patterns. The issue has been resolved in GoLand 2026.2.2.1 and later versions by adding authentication controls to the pprof server.
