Description
Cursor is a code editor built for programming with AI. In versions 1.7.52 and below, manipulating internal settings may lead to RCE. Cursor detects path manipulation via forward slashes (./.cursor/./././././mcp.json etc.), and requires human approval to complete the operation. However, the same kind of manipulation using backslashes was not correctly detected, allowing an attacker who had already achieved prompt injection or some other level of control to overwrite sensitive editor files without approval on Windows machines. This issue is fixed in version 2.0.

Executive Summary

This vulnerability exists in Cursor code editor versions 1.7.52 and below, where manipulating internal settings using backslash path characters on Windows machines bypasses the editor's detection of path manipulation. While forward slash manipulations require human approval, backslash manipulations were not properly detected, allowing an attacker with some level of control (like prompt injection) to overwrite sensitive editor files without approval. This can lead to remote code execution (RCE).

Impact Analysis

If exploited, this vulnerability can allow an attacker to overwrite sensitive files in the Cursor editor without user approval, potentially leading to remote code execution. This means an attacker could execute arbitrary code on your system, compromising confidentiality, integrity, and availability of your environment.

Mitigation Strategies

Upgrade Cursor to version 2.0 or later, as this version fixes the vulnerability related to backslash path manipulation allowing unauthorized file overwrites on Windows machines.
