Critical Vulnerability in Cursor Allows Arbitrary Code Execution via Malicious Git.exe

A critical vulnerability in Cursor allows arbitrary code execution on Windows by exploiting a malicious 'git.exe' in cloned repositories, bypassing user interaction. No patch is available, with workarounds suggesting restricted execution environments and file monitoring.
