CVE-2026-46432Public exploit

Code execution via unconditional remote-code trust

Published Jun 9, 2026 · Updated Jun 9, 2026

Code injection in InternLM LMDeploy 0.12.3 and earlier allows local users to execute Python code through a controlled model path. In lmdeploy/archs.py and lmdeploy/utils.py, model initialization passes that path to Hugging Face loaders with trust_remote_code=True, which downloads and imports repository-supplied Python. Exploitation requires control of the serving process's model path or deployment configuration and runs code with that process's privileges.
