| # ModelScan Bypass PoC — getpass.getuser | |
| Security research for responsible disclosure via Huntr MFV program. | |
| ## Vulnerability | |
| `getpass.getuser` is not in modelscan's `unsafe_globals` blocklist. | |
| modelscan reports "No issues found" but loading triggers username disclosure — returns the current system username. | |
| ## Impact: LOW | |
| ## Reproduction | |
| ```bash | |
| pip install modelscan | |
| modelscan scan -p bypass_poc.pkl | |
| # Output: "No issues found!" | |
| ``` | |
