Cursor < 1.7 RCE (GHSA-xcwh-rrwj-gxc7)

high Nessus Plugin ID 270574

Language:

Synopsis

The Cursor instance installed on the remote host is affected a remote code execution vulnerability.

Description

The version of Cursor installed on the remote host is prior to 1.7. It is, therefore, affected by a remote code execution vulnerability. 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.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade Cursor to version 1.7 or later.
