Windows SmartScreen Security Feature Bypass Vulnerability

Windows SmartScreen, a security feature that warns users about potentially dangerous files and websites, can be bypassed by attackers. This means malicious files could be downloaded and executed without triggering the security warning that normally protects users.

This vulnerability allows an attacker to bypass the SmartScreen reputation check through a crafted file or URI parameter manipulation, enabling delivery of malware without triggering security alerts. Exploitation requires user interaction (file download or opening a link) but can result in arbitrary code execution due to disabled security warnings.
