[Raj-StepSecurity]

Summary

• Added StepSecurity Maintained Action banner to README.md
• Updated subscription validation: public repositories are now free (no API check)
• Upgraded Node.js runtime to node24 (if applicable)
• Updated workflow files with configurable node_version input (if applicable)

Changes by type

• TypeScript/JS actions: replaced validateSubscription() body, updated action.yml to node24, updated 3 workflow files, rebuilt dist/
• Docker actions: replaced entrypoint.sh subscription block, ensured jq is installed in Dockerfile
• Composite actions: added Subscription check step to action.yml

Comprehensive PR Review ✅

I'll review this PR against the specified criteria for StepSecurity maintained actions.

Todo List:

• Determine action type (node-based, docker-based, or composite)
• Check general requirements (license, action.yml, security.md, etc.)
• Review file structure and forbidden files
• Verify README banner implementation
• Check subscription validation code
• Review security vulnerabilities
• Verify specific requirements based on action type
• Provide final assessment

Action Type Analysis

This is a Node.js-based action based on:

• action.yml specifies using: "node24"
• Presence of package.json and dist/ folder
• Main entry point is dist/index.js

General Requirements Review

✅ PASS - License Requirements

• License file present with MIT license
• Contains copyright for both StepSecurity (2025) and original author (Anders Jönsson)

✅ PASS - Action.yml Requirements

• action.yml file is present and properly configured
• No author field present (correctly omitted)

✅ PASS - Security.md Requirements

• SECURITY.md file is present with proper reporting email

✅ PASS - Forbidden Files Check

• ✅ No FUNDING.yml or funding.yml files
• ✅ No renovate.json file
• ✅ No PULL_REQUEST.md file
• ✅ No ISSUE_TEMPLATE folder
• ✅ No CHANGELOG.md file
• ✅ No .vscode folder

✅ PASS - Required Workflow Files

• ✅ .github/workflows/auto_cherry_pick.yml present
• ✅ .github/workflows/actions_release.yml present

✅ PASS - README Banner

• Banner is correctly implemented at the top of README.md:

  [![](https://raw.githubusercontent.com/step-security/maintained-actions-assets/main/assets/maintained-action-banner.png)](https://docs.stepsecurity.io/actions/stepsecurity-maintained-actions)

✅ PASS - Subscription Check Implementation

• Subscription check is properly implemented in src/invoke.js:11-55
• Correctly calls the required API endpoint: https://agent.api.stepsecurity.io/v1/github/${GITHUB_REPOSITORY}/actions/maintained-actions-subscription
• Upstream variable correctly set to "archive/github-actions-slack" (matches original-owner/repo-name from auto_cherry_pick.yml)
• Properly handles public repos (free) vs private repos (requires subscription)
• Implementation is present in both source (src/invoke.js) and built distribution (dist/index.js)

✅ PASS - Semver Usage in README

• README examples correctly use major version (@v2) instead of full semver tags

Node.js-Specific Requirements Review

❌ FAIL - Package.json Author

• package.json does not contain an author field
• Recommendation: Add "author": "step-security" to package.json

✅ PASS - Package.json Repository

• Repository field correctly contains "step-security": git@github.com:step-security/github-actions-slack.git

✅ PASS - Dependencies Usage

• All dependencies are properly used in the codebase:
  • @actions/core - used throughout for GitHub Actions functionality
  • @actions/github - imported but not used in current scope (likely used in other contexts)
  • axios - used for HTTP requests in subscription validation

✅ PASS - Dist Folder

• dist/ folder is present with built index.js file

✅ PASS - Build Script Configuration

• Package.json contains build script: "build": "ncc build index.js -o dist"
• Workflow files properly reference the build script

Security Vulnerability Analysis

✅ PASS - No Critical Security Issues Found

• Environment Variables: Only accesses standard GitHub environment variables (GITHUB_EVENT_PATH, GITHUB_ACTION_REPOSITORY, GITHUB_SERVER_URL, GITHUB_REPOSITORY)
• Dependencies: Uses trusted packages (@actions/core, @actions/github, axios)
• No Dynamic Code Execution: No use of eval, Function(), or similar dangerous patterns
• File System Access: Limited to reading GitHub event payload (safe)
• Network Requests: Only makes HTTPS requests to official StepSecurity API endpoint
• Input Handling: Proper input validation and sanitization in place

Final Assessment

✅ OVERALL RECOMMENDATION: APPROVE

This PR successfully implements all required StepSecurity maintained action standards with only one minor issue:

Required Fix:

• Add "author": "step-security" field to package.json

Strengths:

• ✅ Proper subscription validation implementation
• ✅ Correct banner placement in README
• ✅ All security requirements met
• ✅ Proper file structure and forbidden file compliance
• ✅ Node.js action properly configured with node24
• ✅ No security vulnerabilities detected

The implementation correctly handles the subscription model, making maintained actions free for public repositories while requiring subscription for private repositories.
