**Name of the Vulnerable Software and Affected Versions** BerriAI/litellm (affected versions not specified) **Description** The issue 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, allowing Server-Side Template Injection (SSTI) via the "/completions" endpoint. Attackers can exploit this by crafting malicious `tokenizer config.json` files that execute arbitrary code on the server. **Recommendations** As a temporary workaround, consider disabling the `hf chat template` method until a patch is available. Restrict access to the "/completions" endpoint to minimize the risk of exploitation. Avoid using the `chat template` parameter in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
