description

LightLLM deployments through version 1.2.0 are affected when the router profiler is enabled. A remote unauthenticated attacker may execute code by reaching the exposed profiler service. Exploitation requires the profiling option to be enabled and the service to be network-accessible.

mitigation

Disable the router profiling option where it is not required. If profiling must remain enabled, restrict access to the profiler service to trusted hosts and networks until a fixed LightLLM release is available.
