CVE-2025-64106Network attack vector

User-assisted command execution via trusted-server misclassification

Published Nov 4, 2025 · Updated Nov 4, 2025

Command injection in Anysphere Cursor 1.7.28 and earlier allows remote attackers to execute commands through a crafted MCP deep-link. The MCP installer misclassifies the link as a trusted server, suppressing its warning and hiding the supplied command and arguments. Execution requires the target to open the link and approve the misleading installation dialog, after which the command runs with that user's privileges.
