Description
frp 0.41.0 through 0.71.1 contains a missing authentication vulnerability that allows unauthenticated remote attackers to access pprof debug endpoints because handlers are registered on the root mux outside Basic Authentication. Attackers can query /debug/pprof/ endpoints on frps dashboard or frpc admin listeners to obtain cmdline, goroutine stacks, heap profiles, and trigger CPU profiling.
