Adds support for authenticating against a private npm registry (e.g. Artifactory, GitHub Packages, Nexus) before running pnpm install.

Two new optional inputs are introduced:

  • registry-url — base URL of the private registry
  • registry-token — auth token for that registry (pass via a GitHub secret)

When both are set, the action runs:

pnpm config set "<registry-url>//:_authToken" "<token>"

before pnpm install. If only one of the two is provided, the action fails with a clear error message.

Usage

- uses: your-org/setup@main
  with:
    registry-url: ${{ vars.ARTIFACTORY_URL }}
    registry-token: ${{ secrets.ARTIFACTORY_TOKEN }}

Closes #13

Review Change Stack

📝 Walkthrough

Walkthrough

The action adds optional private-registry inputs. It validates paired credentials, configures pnpm authentication before installation, and adds unit tests for input validation and command argument construction.

Changes

Private registry authentication

Layer / File(s) Summary
Registry input contract
action.yml, src/inputs/index.ts, src/inputs/index.test.mjs
The action defines registry-url and registry-token. validateRegistryInputs rejects incomplete pairs and returns a RegistryConfig when both values exist. getInputs trims and stores the values.
pnpm registry configuration
src/pnpm-install/registry.ts, src/pnpm-install/registry.test.mjs, src/pnpm-install/index.ts, package.json
buildRegistryAuthArgs creates the pnpm authentication command. runPnpmInstall masks the token, executes authentication before installation, and stops on configuration errors. The test script includes the new test suites.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to 68cb1

Private-registry authentication can leave credentials on the runner, expose them to the install process, or transmit them over HTTP. These security issues should be addressed before merge.

Confidence Score: 3/5

The PR is not yet safe to merge because registry credentials can persist beyond the configuring job on reused self-hosted runners.

The shell-injection, log-exposure, malformed-key, and documentation findings were addressed in the current code. All four previous threads were also manually resolved without explanatory replies. One blocking credential-lifecycle issue remains: the new command stores the token in global pnpm configuration without cleanup, allowing later jobs under the same runner account to recover it.

Files Needing Attention: src/pnpm-install/index.ts, dist/index.js

Security Review

The registry token is written to persistent global pnpm configuration without cleanup, allowing credential exposure to later jobs when a self-hosted runner account is reused.

pnpm config set default location auth token user config file documentation

💡 Result:

In current versions of pnpm (v11/v12), the pnpm config set command is designed to store authentication tokens in a secure, global location rather than in project-level files [1][2][3]. When you run pnpm config set to configure an authentication token, it writes to your user-level or global configuration files by default [1][4][3]. This ensures that sensitive credentials are never committed to your project's repository [1][3]. Key points regarding configuration location and authentication: Default Behavior: The pnpm config set command defaults to global scope [2][5]. When setting auth-related keys (like _authToken), pnpm writes these to your global configuration files (such as rc or config.yaml) instead of the project's.npmrc [1][2][4]. Where Auth Tokens are Stored: 1. Global Auth Files: For legacy and npm-compatible settings, pnpm uses the auth.ini or rc file located in your global pnpm configuration directory [1][6]. 2. Global YAML Config: In newer versions (v12.1+), pnpm writes structured _auth settings to the global config.yaml [1][2]. 3. User-level.npmrc: pnpm also reads from the user-level ~/.npmrc as a fallback [1]. How to Set a Token: To set a registry authentication token, use the following command [1][3]: pnpm config set //registry.npmjs.org/:authToken "$NPM_TOKEN" This command will automatically save the token to the global configuration rather than your local project files [1][3]. Important Note for CI/Environment Variables: Because pnpm no longer expands environment variables in repository-level.npmrc files (to prevent security risks), it is recommended to either: - Use pnpm config set to write the token to the global/user config on the build runner before installation [1][4][3]. - Provide the credential via an environment variable directly (e.g., pnpm_config//registry.npmjs.org/:_authToken) [1][3]. - Use the structured _auth setting in the global config.yaml for complex authentication needs [1][7]. You can verify your configuration settings by using pnpm config get [key] [2]. Use pnpm config --help or refer to the official pnpm documentation for more detailed information on specific configuration locations [2][6].

pnpm npmrc _authToken registry URL HTTP HTTPS documentation

💡 Result:

In pnpm, authentication to registries via _authToken is configured in.npmrc files using a URL-scoped format [1][2]. The standard format requires specifying the registry URL (without protocol if using the // host format, or including http/https) followed by the credential key [1][2]. Important Configuration Guidelines: 1. URL Scope Format: To configure an auth token, use the pattern //registry.url.com/:authToken=TOKEN [2]. The registry URL must not include credentials, query strings, or fragments [1]. 2. Environment Variable Expansion Security: As of pnpm v10.34.2 and v11.5.3, pnpm no longer expands environment variables (e.g., ${NPM_TOKEN}) within project-level or workspace-level.npmrc files [2][3][4]. This change was implemented to prevent potential security leaks where a malicious repository could redirect environment-stored secrets to an attacker-controlled registry [3][4]. 3. Trusted Locations: You should place credentials or configuration containing environment variable placeholders in "trusted" locations instead of the repository [3][4]. These locations include: * User-level configuration (~/.npmrc) [1][2][4]. * Global configuration files (e.g., via pnpm config set) [2][3][4]. * CLI options [2][3]. * Directly via environment variables (e.g., pnpm_config//registry.npmjs.org/:_authToken=$TOKEN) [3]. 4. Alternative Auth Format: For CI environments or scenarios where URL-scoped variables are problematic, pnpm supports an _auth setting that accepts a structured value keyed by the registry URL [1]. This acts as an alternative to multiple //host/:_authToken entries [1]. If you attempt to use environment variable expansion in a repository-controlled.npmrc, pnpm will ignore the setting and issue a warning [3][4][5]. You should migrate these settings to your user-level ~/.npmrc or use pnpm config set to store them in your global configuration [2][4].

P1 security Registry token persists globally

pnpm config set is invoked without a project-local or temporary configuration location, and neither the main nor post-action path removes the authentication entry. If a self-hosted runner account is reused across jobs, a later job can read the previous job's registry token from pnpm's persistent global configuration. Use job-local configuration or remove the credential after installation.

How this was verified: The configuration command has no project or temporary location, and neither the main nor post-action path deletes the resulting authentication entry.

GitHub Actions JavaScript action INPUT_REGISTRY-TOKEN @actions/core getInput environment variables hyphen input name official documentation

💡 Result:

In GitHub Actions, input parameters are passed to JavaScript actions as environment variables prefixed with INPUT_ [1][2]. According to official documentation, the runner converts input names to uppercase letters and replaces spaces with underscores (_), but it preserves hyphens (-) [1][2]. For example, an input named registry-token is exposed as the environment variable INPUT_REGISTRY-TOKEN [1][2]. The official @actions/core library's getInput function follows this convention by programmatically accessing the environment variable using the same logic: it uppercases the input name and replaces only spaces with underscores [3][4]. Because the runner does not convert hyphens to underscores, getInput correctly looks up the environment variable containing the hyphen [5][6]. Technical note: While some older discussions or custom implementations incorrectly attempted to replace hyphens with underscores in their lookup logic [7][8][5], this often resulted in failing to read the input because the corresponding environment variable (with the hyphen) was not found [5]. Developers using @actions/core should use the input name as defined in their action.yml file, and the library will handle the environment variable mapping automatically [9][4]. Example usage with @actions/core: const myToken = core.getInput('registry-token'); // Correctly maps to INPUT_REGISTRY-TOKEN [4]

pnpm CLI config set default location global user configuration documentation

💡 Result:

To set a configuration value in the global pnpm configuration file using the CLI, you can use the pnpm config set command with the --global flag or by relying on the default behavior [1][2]. The command syntax is: pnpm config set --global By default, the pnpm config set command targets the global configuration location unless you explicitly specify otherwise [1][2]. Understanding pnpm configuration locations: 1. Global Configuration File: Settings are stored in a YAML file named config.yaml located in the user's home directory. The specific path depends on the operating system or environment variables [1][3]: - Linux: ~/.config/pnpm/config.yaml - macOS: ~/Library/Preferences/pnpm/config.yaml - Windows: ~/AppData/Local/pnpm/config/config.yaml - If the $XDG_CONFIG_HOME environment variable is set, it uses $XDG_CONFIG_HOME/pnpm/config.yaml [1][3]. 2. Legacy/Auth Files: Settings related specifically to authentication and registries are often stored in an INI-formatted rc file located in the same directory as the global config.yaml [1][3][4]. 3. Project-Level Configuration: For project-specific settings, pnpm uses the pnpm-workspace.yaml file located at the root of your project [3][5]. Important Considerations: - CLI Flags: While pnpm config set defaults to global, you can be explicit by using the --global or -g flag [1][2]. - Security: Some settings (such as globalDir, globalBinDir, and various path-related configurations) are restricted from being set in a project's pnpm-workspace.yaml for security reasons. These must be set in the global configuration file or via environment variables to prevent a repository from overriding machine-level state [5][6]. - Verification: You can retrieve the path to your current global configuration file by running pnpm config get globalconfig [2].

Use an isolated pnpm configuration for registry authentication.

pnpm config set stores the token in the user-level configuration by default. This function has no cleanup path when installation succeeds or fails. Use a temporary configuration and remove it in a finally block.

around the configResult spawnSync call to use an isolated temporary pnpm
configuration for registry authentication instead of the user-level
configuration, and ensure that temporary configuration is removed in a finally
block on both successful and failed installation paths.

pnpm npmrc authToken //host/path protocol http https registry URL

💡 Result:

In pnpm, registry authentication via.npmrc is configured using URL-scoped keys that associate a specific registry host with a credential, such as an _authToken [1]. For a registry hosted at a specific URL, the standard format in an.npmrc file is [1]: //host/path/:_authToken=your-token-value Registry URLs used in these keys must be formatted as absolute paths (e.g., //registry.npmjs.org/ or //company-registry.com/api/) [1]. When defining registry URLs in other contexts (such as the _auth setting or registry configuration), they must use the http or https protocol [2]. Important Configuration Notes: 1. Environment Variable Expansion: As of recent pnpm versions, environment variables are no longer expanded within project or workspace.npmrc files to prevent security risks (e.g., secret leakage) [1][3]. 2. Trusted Locations: If you need to use environment variables for authentication, you must define them in trusted locations, such as your user-level ~/.npmrc, global configuration, CLI options, or specific environment variables [1][3]. 3. File-Free Authentication: pnpm now supports configuring registry authentication directly via environment variables using the pnpm_config_//host/path/:_authToken or npm_config_//host/path/:_authToken format [4]. This method is preferred for CI/CD environments as it bypasses the need for a physical.npmrc file and ensures the secret is bound to the correct host [3][4]. 4. Structured _auth: A newer, structured _auth configuration (available in the global config or via the pnpm_configauth environment variable) allows you to define credentials keyed by registry URL, which can also include scope-specific tokens [5][2]. This is an alternative to the traditional URL-scoped syntax [5]. Source references: [5], [1], [3], [4], [2]

🌐 Web query:

site:pnpm.io/npmrc "_authToken" "http" registry request

💡 Result:

In the context of package managers and HTTP registry requests (such as npm, pnpm, or yarn), an authToken is a credential used to authenticate requests to a remote package registry [1]. It typically serves as a bearer token that authorizes the client to perform actions like downloading private packages or publishing modules [1]. Common configurations include: 1. URL-scoped entries: Traditionally, authentication is defined in a configuration file (like.npmrc) using a format keyed by the registry host, such as //registry.npmjs.org/:_authToken=... [1]. 2. Structured auth configurations: Modern tools and CI environments often prefer structured JSON values to avoid issues with special characters in environment variables. For example, some tools support a registry-specific format where the authToken is explicitly mapped to a registry URL: {"//registry.npmjs.org/": {"authToken": "your-token-here"}} [1]. These tokens ensure that requests made by the registry client are authorized by the server, preventing unauthorized access to private package repositories [1].

Enforce HTTPS for registry-url.

The input validation only checks that registry-url and registry-token are set together. It does not reject http: URLs. Since the generated pnpm auth key omits the scheme, an HTTP registry can receive registryToken without transport encryption. Reject non-HTTPS URLs, or add and test a narrow exception for local HTTP registries.

In `@src/pnpm-install/registry.ts` around lines 2 - 4, Validate the parsed URL in
the registry configuration flow before constructing the auth key, requiring the
protocol to be HTTPS and rejecting other schemes; if local HTTP registries are
intentionally supported, allow only that narrowly defined case and cover it with
tests. Keep the existing URL parsing and key generation behavior for accepted
HTTPS registries.
