Description
Cursor is a code editor built for programming with AI. In versions 1.7 and below, a vulnerability in the way Cursor CLI Agent protects its sensitive files (i.e. */.cursor/cli.json) allows attackers to modify the content of the files through prompt injection, thus achieving remote code execution. A prompt injection can lead to full RCE through modifying sensitive files on case-insensitive filesystems. This issue is fixed in a commit, 25b418f, but has yet to be released as of October 3, 2025.

Executive Summary

This vulnerability exists in Cursor CLI Agent versions 1.7 and below, where the protection of sensitive files (such as */.cursor/cli.json) is flawed. Attackers can exploit this by using prompt injection to modify the content of these sensitive files. On case-insensitive filesystems, this modification can lead to remote code execution (RCE), allowing attackers to run arbitrary code remotely.

Impact Analysis

If exploited, this vulnerability can allow an attacker to achieve remote code execution on your system. This means the attacker could run arbitrary commands or code with the privileges of the Cursor CLI Agent, potentially leading to system compromise, data theft, or further attacks.

Mitigation Strategies

Since the vulnerability is fixed in a commit (25b418f) but not yet released, immediate mitigation steps include avoiding use of Cursor CLI Agent versions 1.7 and below, restricting access to sensitive files such as */.cursor/cli.json, and monitoring for suspicious prompt injection attempts. Applying the fix once it is officially released is also recommended.
