AI-Generated

LightLLM versions up to 1.2.0 are vulnerable due to a remote code execution flaw in the router profiler service when the --enable_profiling flag is activated. This vulnerability allows unauthenticated attackers to exploit an exposed RPyC server with enabled pickle deserialization, enabling them to execute arbitrary code via specially crafted serialized objects. Organizations using LightLLM should prioritize immediate remediation to mitigate the risk of potential exploitation.
