Arbitrary code execution via unescaped GGUF filename
Published Aug 26, 2026 · Updated Aug 26, 2026
Code injection in Andyyyy64 whichllm before 0.5.16 allows remote attackers to execute arbitrary code through a malicious GGUF filename. The script generator in cli.py inserts Hub API rfilename values into Python source without escaping, permitting quotes or special characters to terminate the string literal and inject code. Exploitation requires the operator to select an attacker-controlled Hugging Face repository with run or snippet, after which injected code executes locally before model download.
