CVE-2026-33625 Details
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.
A code injection vulnerability has been identified in LMDeploy versions 0.12.1 prior to 0.12.3. The issue resides in the file 'lmdeploy/pytorch/config.py' at line 620, where the 'quant_dtype' value from a model's quantization configuration is passed to 'eval()' without proper validation. This flaw allows an attacker to execute arbitrary Python code by publishing a malicious HuggingFace model with a crafted 'quantization_config.quant_dtype' value. When the model is loaded with LMDeploy, the injected code is executed, leading to potential exploitation.
Users can upgrade to LMDeploy version 0.12.3, which addresses this vulnerability.
