CVE-2026-103040 is an unsafe deserialization vulnerability in LightLLM through version 1.2.0. When LightLLM is started with the --enable_profiling option, its router profiler service exposes an unauthenticated RPyC server that accepts attacker-controlled serialized objects for pickle deserialization through the profiler command queue. A remote attacker can exploit this behavior to execute arbitrary code.

Critical unauthenticated remote code execution in the LightLLM router profiler service caused by unsafe Python pickle deserialization in an exposed RPyC endpoint.
An unauthenticated remote code execution vulnerability in LightLLM through version 1.2.0. When the router profiler service is started with the --enable_profiling flag, its exposed RPyC server permits pickle deserialization of attacker-controlled serialized objects sent to the profiler command queue, enabling arbitrary code execution.
An unauthenticated remote code execution vulnerability affecting LightLLM through version 1.2.0 when its router profiler service is enabled using the --enable_profiling flag. The exposed RPyC service permits pickle deserialization of crafted objects submitted to the profiler command queue, enabling arbitrary code execution.
