# ModelScan Bypass PoC — imp.load_source
Security research for responsible disclosure via Huntr MFV program.
## Vulnerability
`imp.load_source` is not in modelscan's `unsafe_globals` blocklist.
modelscan reports "No issues found" but loading triggers FULL RCE via exec() on arbitrary .py file. Loads and executes any Python file on disk. Deprecated but present in Python 3.8-3.11..
## Impact: CRITICAL
## Reproduction
```bash
pip install modelscan
modelscan scan -p bypass_poc.pkl
# Output: "No issues found!"
```
