CVE-2025-64106

Full vulnerability record from the local CVENow database.

Description

Cursor is a code editor built for programming with AI. In versions 1.7.28 and below, an input validation flaw in Cursor's MCP server installation enables specially crafted deep-links to bypass the standard security warnings and conceal executed commands from users if they choose to accept the server. If an attacker is able to convince a victim to navigate to a malicious deeplink, the victim will not see the correct speedbump modal, and if they choose to accept, will execute commands specified by the attackers deeplink.

En las versiones 1.7.28 e inferiores, una falla de validación de entrada en la instalación del servidor MCP de Cursor permite que deep-links especialmente diseñados omitan las advertencias de seguridad estándar y oculten comandos ejecutados a los usuarios si eligen aceptar el servidor. Si un atacante logra convencer a una víctima de navegar a un deeplink malicioso, la víctima no verá el modal de advertencia (speedbump) correcto, y si elige aceptar, ejecutará comandos especificados por el deeplink del atacante."
