Vulnerability Title
lmdeploy vulnerable to Arbitrary Code Execution via Insecure Deserialization in torch.load()
Source: CVE Program / CVE List V5
Vulnerability Description
LMDeploy is a toolkit for compressing, deploying, and serving LLMs. Prior to version 0.11.1, an insecure deserialization vulnerability exists in lmdeploy where torch.load() is called without the weights_only=True parameter when loading model checkpoint files. This allows an attacker to execute arbitrary code on the victim's machine when they load a malicious .bin or .pt model file. This issue has been patched in version 0.11.1.
