The vulnerability arises from the `hf_chat_template` method processing the `chat_template` parameter from the `tokenizer_config.json` file through the Jinja template engine without proper sanitization. Attackers can exploit this by crafting malicious `tokenizer_config.json` files that execute arbitrary code on the server.\n\n## Affected packages\n\n- `litellm < 1.34.42`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `litellm 1.34.42`","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":53.9,"likelihood":0.3,"exploitation":0,"ransomware":0},"changes":[]}
