F-MFV-004: ModelScan misses NumPy ctypeslib.load_library native-code load
This repository contains a gated proof-of-concept model artifact for a Huntr Model File Vulnerability submission.
Warning: do not load this artifact outside an isolated test environment. The payload is intentionally harmless and writes only local marker files during controlled reproduction, but it demonstrates a model-load execution path.
Target
- Finding:
F-MFV-004 - Target: Joblib / ModelScan
- Scanner: ModelScan
0.8.8
Summary
The Joblib artifact embeds a harmless shared library and loads it through numpy.ctypeslib.load_library during model load while ModelScan 0.8.8 reports zero issues.
