CVE-2026-46517

Code execution via implicit remote model trust

Published Jun 9, 2026 · Updated Jun 9, 2026

Code injection in InternLM LMDeploy 0.12.3 and earlier allows attackers to execute Python when a user loads a malicious model repository. The get_model_arch path and related loaders pass trust_remote_code=True to Hugging Face from_pretrained calls, which import repository-supplied configuration modules. Exploitation requires a user or pipeline to select an attacker-controlled repository; its top-level Python runs with the LMDeploy process user's permissions.
