CVE-2025-59944

HIGH

Cursor < 1.6.23 - Remote Code Execution via Case-Sensitive File Protection Bypass

Title source: llm
STIX 2.1

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.
