Cursor vulnerabilities

Cursor IDE for macOS allows an agent running in Auto-Run Sandbox mode, when Docker Desktop and the Dev Containers CLI are installed, to launch a privileged container and mount Docker's virtiofs0, granting…

Cursor IDE for macOS allows an agent running in Auto-Run Sandbox mode to replace a virtual environment's Python executable with a malicious wrapper that the Microsoft Python extension invokes outside the…

Cursor runs agent terminal commands in a sandbox by default, and the sandbox grants write access to the command's working directory.

The Cursor Desktop could execute workspace-defined Claude hook commands from .claude/settings.local.json without dedicated user approval.

A vulnerability in the Cursor CLI Beta allowed an attacker to achieve remote code execution through the MCP (Model Context Protocol) server mechanism by uploading a malicious MCP configuration in…

An input validation flaw in Cursor's MCP server installation enables specially crafted deep-links to bypass the standard security warnings and conceal executed commands from users if they choose to accept…

When MCP uses OAuth authentication with an untrusted MCP server, an attacker can impersonate a malicious MCP server and return crafted, maliciously injected commands during the interaction process, leading…

Versions 1.6 and below are vulnerable to Remote Code Execution (RCE) attacks through Visual Studio Code Workspaces.

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…

Attackers can achieve remote and persistent code execution by modifying an already trusted MCP configuration file inside a shared GitHub repository or editing the file locally on the target's machine.
