**Name of the Vulnerable Software and Affected Versions**
whichllm versions prior to 0.5.16
**Description**
A code injection issue exists in the `run` and `snippet` commands. A remote attacker controlling a HuggingFace repository can achieve arbitrary code execution by crafting a malicious GGUF filename containing double quotes or other special characters. The script generation function in `cli.py` interpolates values derived from HuggingFace, specifically the `rfilename` field from the Hub API siblings, directly into Python source code without escaping. This allows the crafted filename to break out of the generated string literal and execute injected code on the user's machine before any model download occurs.
**Recommendations**
Update to version 0.5.16 or later.
