GHSA-m549-qq94-fvhg: LMDeploy: Arbitrary code execution via hardcoded trust_remote_code=True in lmdeploy model initialization

LMDeploy, a model serving tool, hardcodes `trust_remote_code=True` (a setting that allows executing custom Python code from downloaded models) when loading models from HuggingFace. An attacker who can control which model path the system loads could point it to a malicious model repository, causing arbitrary code execution (running any commands they want) with the privileges of the LMDeploy server process. This affects LMDeploy version 0.12.3 and earlier.
