CVE-2025-59944

Cursor IDE: Sensitive File Overwrite Bypass is Possible

State: Published
Severity: 8.1 High
Published: Oct 3, 2025
Updated: Oct 3, 2025
Reserved: Sep 23, 2025

Description

Cursor is a code editor built for programming with AI. Versions 1.6.23 and below contain case-sensitive checks in the way Cursor IDE protects its sensitive files (e.g., */.cursor/mcp.json), which allows attackers to modify the content of these files through prompt injection and achieve remote code execution. A prompt injection can lead to full RCE through modifying sensitive files on case-insensitive fileystems. This issue is fixed in version 1.7.
