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.

Executive Summary

This vulnerability is an input validation flaw in Cursor's MCP server installation (versions 1.7.28 and below) that allows specially crafted deep-links to bypass standard security warnings. When a victim navigates to such a malicious deep-link and accepts the prompt, the expected security warning modal is not shown correctly, and commands specified by the attacker are executed without the user's proper awareness.

Impact Analysis

If exploited, this vulnerability can lead to the execution of arbitrary commands on the victim's system without proper user consent or awareness. This can result in unauthorized access, data compromise, or system manipulation, potentially causing significant harm depending on the commands executed by the attacker.
