Cursor is a code editor built for programming with AI. Prior to 3.0.0, 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 read and write access to the user's home directory and enabling host command execution with the user's privileges without an additional permission prompt. This issue is fixed in version 3.0.0.
