Description
Cursor is a code editor built for programming with AI. In versions prior to 3.0.0, the Cursor Desktop could execute workspace-defined Claude hook commands from .claude/settings.local.json without dedicated user approval. A malicious workspace or agent-created file could configure hooks that run local commands in the user's context when an agent turn ends. This could allow sandbox escape, persistence across turns, local data access, or follow-on compromise. This issue has been fixed in version 3.0.0.

Executive Summary

This vulnerability affects Cursor, a code editor built for programming with AI, in versions prior to 3.0.0. The Cursor Desktop could execute workspace-defined Claude hook commands from a configuration file (.claude/settings.local.json) without requiring explicit user approval. A malicious workspace or file created by an agent could configure hooks that run local commands in the user's context when an agent turn ends.

This behavior could allow an attacker to escape the sandbox environment, maintain persistence across agent turns, access local data, or perform further compromise on the affected system.

The issue has been fixed in version 3.0.0 of Cursor.

Impact Analysis

This vulnerability can have serious impacts including allowing an attacker to execute arbitrary local commands on your system without your explicit consent.

Potential impacts include sandbox escape, which means the attacker can break out of restricted environments, persistence across agent turns, unauthorized access to local data, and further compromise of your system.

Mitigation Strategies

To mitigate this vulnerability, upgrade Cursor Desktop to version 3.0.0 or later, where the issue has been fixed.
