HighCVSS: 8.6Last Updated: March 18, 2026
Open Neural Network Exchange (ONNX) - Authentication Bypass
Overview
Open Neural Network Exchange (ONNX) <= 1.20.1 contains a security control bypass caused by improper logic in repository trust verification in onnx.hub.load(), letting attackers perform zero-interaction supply-chain attacks and exfiltrate sensitive files when loading models with silent=True.
Severity & Score
Impact
Attackers can silently exfiltrate sensitive files from victim machines during model loading, leading to data theft and supply-chain compromise.
Mitigation
No patched versions available; monitor for updates and avoid using silent=True with untrusted models.
