Description
Cursor is a code editor built for programming with AI. In versions 1.7.44 and below, various NTFS path quirks allow a prompt injection attacker to circumvent sensitive file protections and overwrite files which Cursor requires human approval to overwrite. Modification of some of the protected files can lead to RCE. Must be chained with a prompt injection or malicious model attach. Only affects systems supporting NTFS. This issue is fixed in version 2.0.

CWE ID Description
CWE-94 The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
CWE-22 The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

Executive Summary

This vulnerability affects Cursor code editor versions 1.7.44 and below, where certain NTFS path quirks allow an attacker using prompt injection to bypass protections on sensitive files. This enables the attacker to overwrite files that normally require human approval to modify. Some of these files, if altered, can lead to remote code execution (RCE). The exploit requires chaining with a prompt injection or a malicious model attachment and only affects systems using NTFS. The issue is fixed in version 2.0.

Impact Analysis

This vulnerability can allow an attacker to overwrite protected files within the Cursor code editor without user approval, potentially leading to remote code execution on the affected system. This could result in unauthorized control over the system, data compromise, or further exploitation.

Mitigation Strategies

Upgrade Cursor to version 2.0 or later, as this version fixes the vulnerability. Additionally, avoid using vulnerable versions (1.7.44 and below) on systems supporting NTFS until the upgrade is applied.
