Affected scope and exposure questions

The current feed maps InternLM/lmdeploy (generic), lmdeploy (pip). Check affected ranges and fixed versions before updating.

Mapped affected packages and fixed versions
Package	Affected range	Fixed version
InternLM/lmdeploygeneric	>= 0.12.1, < 0.12.3	Not reported
lmdeploypip	>=0.12.1,<0.12.3	0.12.3

Recommended response

Check inventory. Check lockfiles and deployed manifests for InternLM/lmdeploy, lmdeploy.
Review the reported fix. Update lmdeploy to 0.12.3 if you use the affected versions. Test the change in a non-production environment first.

Sources and claim methodology

Upstream source description

LMDeploy is a toolkit for compressing, deploying, and serving large language models. Versions 012.1 through 0.12.2 contain a code injection vulnerability in `lmdeploy/pytorch/config.py` line 620 that allows an attacker to execute arbitrary Python code by publishing a malicious HuggingFace model with a crafted `quantization_config.quant_dtype` value. When a user loads the model with lmdeploy, the `quant_dtype` is passed to `eval(f'torch.{quant_dtype}')` without any validation. Version 0.12.3 contains a patch.
