PickleScan Panic: Critical Vulnerabilities Turn Python Security Sour
Three critical zero-day vulnerabilities in PickleScan have been revealed, allowing attackers to bypass safeguards and distribute malicious machine learning models. With a CVSS score of 9.3, these flaws highlight the systemic risks of relying on a single scanning tool and the divergent behaviors in file handling between security tools and ML frameworks.
Hot Take:
PickleScan vulnerabilities are the cybersecurity equivalent of putting a “Do Not Enter” sign on a revolving door. While the scanner’s got its eyes wide shut, the hackers are waltzing right through with their malicious payloads. So much for being the security bouncer of the Python world!
Key Points:
- Three zero-day vulnerabilities with a CVSS rating of 9.3 found in PickleScan
- Flaws allow attackers to bypass model-scanning safeguards
- First flaw involves misclassified file extensions; PyTorch loads the malicious file anyway
- Second flaw exploits ZIP archive CRC errors; attackers can upload models unnoticed
- Third flaw lets attackers evade blacklist checks through subclassing
