🚨 CRITICAL: A Cursor IDE vulnerability allows arbitrary code execution on Windows simply by opening a malicious repository. Tracked as CVE-2026-63093, the binary planting flaw lets an attacker place a malicious git.exe in the repository root. Cursor can then automatically execute it with the user’s privileges — no prompt injection, AI agent, or additional interaction required. Mindgard disclosed the issue after reporting it to Cursor in December 2025. #Cursor #CVE #RCE #CyberSecurity #DevSecOps #Infosec
