ModelScan Bypass β Arbitrary Code Execution via joblib Deserialization
Summary
This repository contains a proof-of-concept .joblib model file that achieves arbitrary code execution when loaded with joblib.load(), while evading ModelScan v0.8.8 detection entirely.
Reproduction
# Step 1: Scan the file (reports clean)
# pip install modelscan
# modelscan scan --path model.joblib
# Step 2: Load the file (executes code)
import joblib
joblib.load("model.joblib")
