CVE-2026-33625: Internlm Lmdeploy

High severity, CVSS 8.8. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Internlm Lmdeploy: from 0.12.1, before 0.12.3 (fixed in 0.12.3)
