-# `nvm` Threat Model
-
-## Introduction
-
-Threat model analysis assists organizations to proactively identify potential security threats and vulnerabilities, enabling them to develop effective strategies to mitigate these risks before they are exploited by attackers.
-Furthermore, this often helps to improve the overall security and resilience of a system or application.
-
-The aim of this section is to facilitate the identification of potential security threats and vulnerabilities that may be exploited by adversaries, along with possible outcomes and appropriate mitigations.
-
-## Relevant assets and threat actors
-
-The following assets are considered important for the `nvm` project:
-  - `nvm` source code and project documentation
-  - Underlying `nvm` dependencies
-  - `nvm` development infrastructure
-  - `nvm` installed devices including servers
-
-The following threat actors are considered relevant to the `nvm` application:
-  - External malicious attackers
-  - Internal malicious attackers
-  - Services
-  - Malicious insider actors
-  - Third-party libraries
-
-## Attack surface for external/internal attackers and services
-
-In threat modeling, an attack surface refers to any possible point of entry that an attacker might use to exploit a system or application.
-This includes all the paths and interfaces that an attacker may use to access, manipulate or extract sensitive data from a system.
-By understanding the attack surface, organizations are typically able to identify potential attack vectors and implement appropriate countermeasures to mitigate risks.
-
-In the following diagrams, _External Malicious Attacker_ applies to threat actors who do not yet have direct access to the `nvm` application and the underlying operating system, while the _Internal Malicious Attacker_ applies to an attacker with access to the device (computer, server), potentially after successfully exploiting a threat from the _External Malicious Attacker_ scenario.
-**Please note that some of the external threats may be also exploitable from internal threats and vice versa.**
-
-<img src="./external-threat-actor.png" alt="Fig.: Possible attacks from internal and external threat actors and services" />
-Fig.: Possible attacks from internal and external threat actors and services
-
-## Identified threats
-
-The identified threats against the `nvm` application are as follows:
-
-### Threat ID 1: `nvm` commands
-
-Overview: The `nvm` commands and subcommands take user input for handling and executing appropriate functions from the project directory (or any parent directory).
-When user-controlled inputs are not adequately validated and later passed to the `nvm` functions as a part of a command, an attacker might be able to execute operating system commands triggered by any parsing functionality.
-
-Possible Outcome: Attacks against `nvm` commands could lead to unauthorized access to user data or unauthorized access to the device (i.e. laptop or server, depending on where `nvm` is installed), resulting in loss of user private data stored on the device, among other possibilities.
-
-Recommendation: Input validation should be implemented to prevent attackers from requesting operating system commands.
-Similarly, secure coding practices ought to be in place to minimize the risk of buffer overflow vulnerabilities.
-
-### Threat ID 2: URI scheme
-
-Overview: `nvm` commands heavily use the [Secure HyperText Transfer](https://datatracker.ietf.org/doc/html/rfc2660) protocol for `nvm` related actions.
-Missing [scheme](https://datatracker.ietf.org/doc/html/rfc3986#section-3.1) validation for any `nvm` command might result in file retrieval, enumeration, file overwrite, or [path traversal](https://owasp.org/www-project-web-security-testing-guide/latest/4-Web_Application_Security_Testing/05-Authorization_Testing/01-Testing_Directory_Traversal_File_Include) attacks.
-An example of this could be path validation for [`nvm_download`](https://github.com/nvm-sh/nvm/blob/ef7fc2f2c06ad75fe7fbabf28d427561ae7b007d/nvm.sh#L118), among many other possibilities.
-
-Possible Outcome: Security misconfiguration flaws for URI scheme may lead to unauthorized access to user data, as well as data integrity compromises.
-
-Recommendation: Adequate input validation should be implemented to prevent attackers from enumerating, retrieving and writing to application files and paths.
-
-### Threat ID 3: Communication channel
-
-Overview: The `nvm` commands and its subcommands use network protocol to communicate with external services.
-Insecure communication may allow malicious attackers to perform [_Man-in-the-Middle_](https://owasp.org/www-community/attacks/Manipulator-in-the-middle_attack) attacks in order to manipulate the data sent during the users’ active connection.
-
-Possible Outcome: Usage of plaintext communication protocols, like HTTP could lead to data sniffing and modification through insecure communications channels.
-
-Recommendation: Mitigation countermeasures such as data encryption should be in place to prevent data manipulation via insecure communication channels.
-
-### Threat ID 4: Environment variables
-
-Overview: Each `nvm` installation defines its environment variables, which should be secured from internal malicious attackers, preventing access control attack vectors.
-Missing stringent restrictions on setting variables, might allow attackers to prepare various targeted attacks against other local users, who use `nvm` in their user space.
-For example, [_Privilege Escalation_](https://owasp.org/Top10/A01_2021-Broken_Access_Control/), [_Command Injection_](https://cwe.mitre.org/data/definitions/77.html), as well as many other parser-related attacks.
-
-Possible Outcome: Attacks against environment variables could lead to unauthorized access to the user space, resulting in the loss of user private data and disruptions in service availability.
-
-Recommendation: Adequate hardening of configuration file permissions should be in place for all relevant configuration files, as this provides protection against attackers able to manipulate variables and inject malicious code.
-
-## Attack surface for malicious insider actors and third-party libraries
-
-The following diagram summarizes the main possible threats against the `nvm` project from malicious insider actors and third-party libraries:
-
-<img src="./insider-threat-actor-and-libs.png" alt="Fig.: Possible attacks from insider threat actors and third-party libraries" />
-Fig.: Possible attacks from insider threat actors and third-party libraries
-
-The identified threats against the `nvm` project are as follows:
-
-### Threat ID 1: Insider threat actor
-
-**Overview**: An insider threat actor, such as an `nvm` project contributor or employee with access to the code base, might abuse their role in the organization to modify the `nvm` application source code.
-For example, intentionally adding malicious code snippets, clearing logs after being written and/or modifying specific sections of the documentation.
-
-**Possible Outcome**: Reputation damage, financial losses.
-
-**Recommendation**: Secure coding practices, code reviews, automated code scanning and separation of duties (i.e. requiring at least two developers to approve any code change) are potentially useful security controls to identify and mitigate vulnerabilities that may be introduced by an insider threat actor.
-
-### Threat ID 2: Third-party libraries
-
-**Overview**: Please note that while `nvm` does not currently make use of any third-party libraries, this might become an attack vector if that changes in the future.
-Third-party libraries may introduce potential risks related to maintaining security requirements by third-party vendors.
-As a result, third-party libraries used by the `nvm` project, might contain vulnerabilities, such as [_Buffer Overflows_](https://owasp.org/www-community/vulnerabilities/Buffer_Overflow), [_Format String Vulnerabilities_](https://owasp.org/www-community/attacks/Format_string_attack), as well as many other types of weaknesses that, in a worst-case scenario may lead to _Remote Code Execution_ (_RCE_).
-Additionally, the maintainer of a third-party dependency might introduce a vulnerability on purpose, or be compromised by an attacker that subsequently introduces vulnerable code.
-
-**Possible Outcome**: Code vulnerabilities may lead to unauthorized access to user data, loss of user private data, service disruptions and reputation damage.
-
-**Recommendation**: Third-party libraries should be kept up-to-date, applying patches to address publicly known vulnerabilities in a timely fashion.
-Monitoring and logging capabilities should also be in place to detect and respond to potential attacks.
-SLSA compliance may also be considered for further supply chain security hardening.

-# nvm Coding Agent Instructions
-
-This document provides guidance for AI coding agents when working with the Node Version Manager (nvm) codebase.
-
-## Overview
-
-nvm is a version manager for Node.js, implemented as a POSIX-compliant function that works across multiple shells (sh, dash, bash, ksh, zsh). The codebase is primarily written in shell script and emphasizes portability and compatibility.
-
-### Core Architecture
-
-- **Main script**: `nvm.sh` - Contains all core functionality and the main `nvm()` function
-- **Installation script**: `install.sh` - Handles downloading and installing nvm itself
-- **Execution wrapper**: `nvm-exec` - Allows running commands with specific Node.js versions
-- **Bash completion**: `bash_completion` - Provides tab completion for bash users
-- **Tests**: Comprehensive test suite in `test/` directory using the [urchin](https://www.npmjs.com/package/urchin) test framework
-
-## Key Files and Their Purposes
-
-### `nvm.sh`
-The core functionality file containing:
-- Main `nvm()` function (starts around line 3000)
-- All internal helper functions (prefixed with `nvm_`)
-- Command implementations for install, use, ls, etc.
-- Shell compatibility logic
-- POSIX compliance utilities
-
-### `install.sh`
-Handles nvm installation via curl/wget/git:
-- Downloads nvm from GitHub
-- Sets up directory structure
-- Configures shell integration
-- Supports both git clone and script download methods
-
-### `nvm-exec`
-Simple wrapper script that:
-- Sources nvm.sh with `--no-use` flag
-- Switches to specified Node version via `NODE_VERSION` env var or `.nvmrc`
-- Executes the provided command with that Node version
-
-## Top-Level nvm Commands and Internal Functions
-
-### Core Commands
-
-#### `nvm install [version]`
-- **Internal functions**: `nvm_install_binary()`, `nvm_install_source()`, `nvm_download_artifact()`
-- Downloads and installs specified Node.js version
-- Automatically `nvm use`s that version after installation
-- Supports LTS versions, version ranges, and built-in aliases (like `node`, `stable`) and user-defined aliases
-- Can install from binary or compile from source
-- When compiling from source, accepts additional arguments that are passed to the compilation task
-
-#### `nvm use [version]`
-- **Internal functions**: `nvm_resolve_alias()`, `nvm_version_path()`, `nvm_change_path()`
-- Switches current shell to use specified Node.js version
-- Updates PATH environment variable
-- Supports `.nvmrc` file integration
-
-#### `nvm ls [pattern]`
-- **Internal functions**: `nvm_ls()`, `nvm_tree_contains_path()`
-- Lists installed Node.js versions
-- Supports pattern matching and filtering
-- Shows current version and aliases
-
-#### `nvm ls-remote [pattern]`
-- **Internal functions**: `nvm_ls_remote()`, `nvm_download()`, `nvm_ls_remote_index_tab()`
-- Lists available Node.js versions from nodejs.org and iojs.org, or the env-var-configured mirrors
-- Supports LTS filtering and pattern matching
-- Downloads version index on-demand
-
-#### `nvm alias [name] [version]`
-- **Internal functions**: `nvm_alias()`, `nvm_alias_path()`
-- Creates text files containing the mapped version, named as the alias name
-- Special aliases: `default`, `node`, `iojs`, `stable`, `unstable` (note: `stable` and `unstable` are deprecated, from node's pre-v1 release plan)
-- Stored in `$NVM_DIR/alias/` directory
-
-#### `nvm current`
-- **Internal functions**: `nvm_ls_current()`
-- Shows currently active Node.js version
-- Returns "system" if using system Node.js
-
-#### `nvm which [version]`
-- **Internal functions**: `nvm_version_path()`, `nvm_resolve_alias()`
-- Shows path to specified Node.js version
-- Resolves aliases and version strings
-
-### Utility Commands
-
-#### `nvm cache clear|dir`
-- Cache management for downloaded binaries and source code
-- Clears or shows cache directory path
-
-#### `nvm debug`
-- Diagnostic information for troubleshooting
-- Shows environment, tool versions, and paths
-
-#### `nvm deactivate`

-```
-
-### Running Tests
-
-#### Install Dependencies
-```bash
-npm install  # Installs urchin, semver, and replace tools
-```
-
-#### Run All Tests
-```bash
-npm test               # Runs tests in current shell (sh, bash, dash, zsh, ksh)
-make test              # Runs tests in all supported shells (sh, bash, dash, zsh, ksh)
-make test-sh           # Runs tests only in sh
-make test-bash         # Runs tests only in bash
-make test-dash         # Runs tests only in dash
-make test-zsh          # Runs tests only in zsh
-make test-ksh          # Runs tests only in ksh
-```
-
-#### Run Specific Test Suites
-```bash
-make TEST_SUITE=fast test        # Only fast tests
-make TEST_SUITE=slow test        # Only slow tests
-make SHELLS=bash test            # Only bash shell
-```
-
-#### Individual Test Execution
-```bash
-./test/fast/Unit\ tests/nvm_get_arch     # Run single test (WARNING: This will exit/terminate your current shell session)
-./node_modules/.bin/urchin test/fast/                        # Run fast test suite
-./node_modules/.bin/urchin 'test/fast/Unit tests/nvm_get_arch'  # Run single test safely without shell termination
-./node_modules/.bin/urchin test/slow/                        # Run slow test suite
-./node_modules/.bin/urchin test/sourcing/                    # Run sourcing test suite
-```
-
-### Test Writing Guidelines
-- Tests should work across all supported shells (sh, bash, dash, zsh, ksh)
-- Define and use a `die()` function for test failures
-- Clean up after tests in cleanup functions
-- Mock external dependencies when needed
-- Place mocks in `test/mocks/` directory
-- Mock files should only be updated by the existing `update_test_mocks.sh` script, and any new mocks must be added to this script
-
-## Shell Environment Setup
-
-### Supported Shells
-- **bash** - Full feature support
-- **zsh** - Full feature support
-- **dash** - Basic POSIX support
-- **sh** - Basic POSIX support
-- **ksh** - Limited support (experimental)
-
-### Installing Shell Environments
-
-#### Ubuntu/Debian
-```bash
-sudo apt-get update
-sudo apt-get install bash zsh dash ksh
-# sh is typically provided by dash or bash and is available by default
-```
-
-#### macOS
-```bash
-# bash and zsh are available by default, bash is not the default shell for new user accounts
-# Install other shells via Homebrew
-brew install dash ksh
-# For actual POSIX sh (not bash), install mksh which provides a true POSIX sh
-brew install mksh
-```
-
-#### Manual Shell Testing
-```bash
-# Test in specific shell
-bash -c "source nvm.sh && nvm --version"
-zsh -c "source nvm.sh && nvm --version"
-dash -c ". nvm.sh && nvm --version"
-sh -c ". nvm.sh && nvm --version"          # On macOS: mksh -c ". nvm.sh && nvm --version"
-ksh -c ". nvm.sh && nvm --version"
-```
-
-### Shell-Specific Considerations
-- **zsh**: Requires basically any non-default zsh option to be temporarily unset to restore POSIX compliance
-- **dash**: Limited feature set, avoid bash-specific syntax
-- **ksh**: Some features may not work, primarily for compatibility testing
-
-## CI Environment Details
-
-### GitHub Actions Workflows
-
-#### `.github/workflows/tests.yml`
-- Runs test suite across multiple shells and test suites
-- Uses `script` command for proper TTY simulation
-- Matrix strategy covers shell × test suite combinations
-- Excludes install_script tests from non-bash shells
-
-#### `.github/workflows/shellcheck.yml`
-- Lints all shell scripts using shellcheck
-- Tests against multiple shell targets (bash, sh, dash, ksh)
-  - Note: zsh is not included due to [shellcheck limitations](https://github.com/koalaman/shellcheck/issues/809)
-- Uses Homebrew to install latest shellcheck version
-
-#### `.github/workflows/lint.yml`
-- Runs additional linting and formatting checks
-- Validates documentation and code style
-
-### Travis CI (Legacy)
-- Configured in `.travis.yml`
-- Tests on multiple Ubuntu versions
-- Installs shell environments via apt packages
-
-### CI Test Execution
-```bash
-# Simulate CI environment locally
-unset TRAVIS_BUILD_DIR  # Disable Travis-specific logic
-unset GITHUB_ACTIONS    # Disable GitHub Actions logic
-make test
-```
-
-## Setting Up shellcheck Locally
-
-### Installation
-
-#### macOS (Homebrew)
-```bash
-brew install shellcheck
-```
-
-#### Ubuntu/Debian
-```bash
-sudo apt-get install shellcheck
-```
-
-#### From Source
-```bash
-# Download from https://github.com/koalaman/shellcheck/releases
-wget https://github.com/koalaman/shellcheck/releases/download/latest/shellcheck-latest.linux.x86_64.tar.xz
-tar -xf shellcheck-latest.linux.x86_64.tar.xz
-sudo cp shellcheck-latest/shellcheck /usr/local/bin/
-```
-
-### Usage
-
-#### Lint Main Files
-```bash
-shellcheck -s bash nvm.sh
-shellcheck -s bash install.sh
-shellcheck -s bash nvm-exec
-shellcheck -s bash bash_completion
-```
-
-#### Lint Across Shell Types
-```bash
-shellcheck -s sh nvm.sh      # POSIX sh
-shellcheck -s bash nvm.sh    # Bash extensions
-shellcheck -s dash nvm.sh    # Dash compatibility
-shellcheck -s ksh nvm.sh     # Ksh compatibility
-```
-
-#### Common shellcheck Directives in nvm
-- `# shellcheck disable=SC2039` - Allow bash extensions in POSIX mode
-- `# shellcheck disable=SC2016` - Allow literal `$` in single quotes
-- `# shellcheck disable=SC2001` - Allow sed usage instead of parameter expansion
-- `# shellcheck disable=SC3043` - Allow `local` keyword (bash extension)
-
-### Fixing shellcheck Issues
-1. **Quoting**: Always quote variables: `"${VAR}"` instead of `$VAR`
-2. **POSIX compliance**: Avoid bash-specific features in portable sections
-3. **Array usage**: Use `set --` for positional parameters instead of arrays, which are not supported in POSIX
-4. **Local variables**: Declared with `local FOO` and then initialized on the next line (the latter is for ksh support)
-
-## Development Best Practices
-
-### Code Style
-- Use 2-space indentation
-- Follow POSIX shell guidelines for portability
-- Prefix internal functions with `nvm_`
-- Use `nvm_echo` instead of `echo` for output
-- Use `nvm_err` for error messages
-
-### Compatibility
-- Test changes across all supported shells
-- Avoid bash-specific features in core functionality
-- Use `nvm_is_zsh` to check when zsh-specific behavior is needed
-- Mock external dependencies in tests
-
-### Performance
-- Cache expensive operations (like remote version lists)
-- Use local variables to avoid scope pollution
-- Minimize subprocess calls where possible
-- Implement lazy loading for optional features
-
-### Debugging
-- Use `nvm debug` command for environment information
-- Enable verbose output with `set -x` during development
-- Test with `NVM_DEBUG=1` environment variable
-- Check `$NVM_DIR/.cache` for cached data issues
-
-## Common Gotchas
-
-1. **PATH modification**: nvm modifies PATH extensively; be careful with restoration
-2. **Shell sourcing**: nvm must be sourced, not executed as a script
-3. **Version resolution**: Aliases, partial versions, and special keywords interact complexly
-4. **Platform differences**: Handle differences between Linux, macOS, and other Unix systems
-5. **Network dependencies**: Many operations require internet access for version lists
-6. **Concurrent access**: Multiple shells can conflict when installing versions simultaneously
-
-## Windows Support
-
-nvm works on Windows via several compatibility layers:
-
-### WSL2 (Windows Subsystem for Linux)
-- Full nvm functionality available
-- **Important**: Ensure you're using WSL2, not WSL1 - see [Microsoft's WSL2 installation guide](https://docs.microsoft.com/en-us/windows/wsl/install) for up-to-date instructions
-- Install Ubuntu or other Linux distribution from Microsoft Store
-- Follow Linux installation instructions within WSL2
-
-### Cygwin
-- POSIX-compatible environment for Windows
-- Download Cygwin from [cygwin.com](https://www.cygwin.com/install.html) and run the installer
-- During installation, include these packages: bash, curl, git, tar, and wget
-- May require additional PATH configuration
-
-### Git Bash (MSYS2)
-- Comes with Git for Windows
-- Limited functionality compared to full Linux environment
-- Some features may not work due to path translation issues, including:
-  - Binary extraction paths may be incorrectly translated
-  - Symlink creation may fail
-  - Some shell-specific features may behave differently
-  - File permissions handling differs from Unix systems
-
-### Setup Instructions for Windows
-
-#### WSL2 (recommended)
-1. Install WSL2 using the official Microsoft guide: https://docs.microsoft.com/en-us/windows/wsl/install
-2. Install Ubuntu or preferred Linux distribution from Microsoft Store
-3. Follow standard Linux installation within WSL2
-
-#### Git Bash
-1. Install Git for Windows (includes Git Bash) from https://git-scm.com/download/win
-2. Open Git Bash terminal
-3. Run nvm installation script
-
-#### Cygwin
-1. Download and install Cygwin from https://www.cygwin.com/install.html
-2. Include bash, curl, git, tar, and wget packages during installation
-3. Run nvm installation in Cygwin terminal
-
-This guide should help AI coding agents understand the nvm codebase structure, testing procedures, and development environment setup requirements.

-#### Installing in Docker
-
-When invoking bash as a non-interactive shell, like in a Docker container, none of the regular profile files are sourced. In order to use `nvm`, `node`, and `npm` like normal, you can instead specify the special `BASH_ENV` variable, which bash sources when invoked non-interactively.
-
-```Dockerfile
-# Use bash for the shell
-SHELL ["/bin/bash", "-o", "pipefail", "-c"]
-
-# Create a script file sourced by both interactive and non-interactive bash shells
-ENV BASH_ENV /home/user/.bash_env
-RUN touch "${BASH_ENV}"
-RUN echo '. "${BASH_ENV}"' >> ~/.bashrc
-
-# Download and install nvm
-RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.4/install.sh | PROFILE="${BASH_ENV}" bash
-RUN echo node > .nvmrc
-RUN nvm install
-```

-##### Installing in Docker for CICD-Jobs
-
-More robust, works in CI/CD-Jobs. Can be run in interactive and non-interactive containers.
-See https://github.com/nvm-sh/nvm/issues/3531.
-
-```Dockerfile

-
-# install curl
-RUN apt update && apt install curl -y
-
-# install nvm
-RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.4/install.sh | bash

-# set env
-ENV NVM_DIR=/root/.nvm
-
-# install node
-RUN bash -c "source $NVM_DIR/nvm.sh && nvm install $NODE_VERSION"
-
-# set ENTRYPOINT for reloading nvm-environment
-ENTRYPOINT ["bash", "-c", "source $NVM_DIR/nvm.sh && exec \"$@\"", "--"]
-
-# set cmd to bash
-CMD ["/bin/bash"]
-
-```
-
-This example defaults to installation of nodejs version 20.x.y. Optionally you can easily override the version with docker build args like:
-```
-docker build -t nvmimage --build-arg NODE_VERSION=19 .
-```
-
-After creation of the image you can start container interactively and run commands, for example:
-```
-docker run --rm -it nvmimage
-
-root@0a6b5a237c14:/# nvm -v
-0.40.4
-
-root@0a6b5a237c14:/# node -v
-v19.9.0
-
-root@0a6b5a237c14:/# npm -v
-9.6.3
-```
-
-Noninteractive example:
-```
-user@host:/tmp/test $ docker run --rm -it nvmimage node -v
-v19.9.0
-user@host:/tmp/test $ docker run --rm -it nvmimage npm -v
