Using Amazon Q Developer for GitHub

Amazon Q Developer1 is an AI-powered assistant that integrates directly into your GitHub workflow, enhancing your development process with intelligent features for code development, review, and transformation.

Slash Commands

Command Description
/q <message> Chat with the agent to ask questions or request revisions
/q review Requests an Amazon Q powered code review
/q help Displays usage information

Features

Agentic Chat
Enables interactive conversation with Amazon Q to ask questions about the pull request or request specific revisions. Use /q <message> in comment threads or the review body to engage with the agent directly.

Code Review
Analyzes pull requests for code quality, potential issues, and security concerns. Provides feedback and suggested fixes. Automatically triggered on new or reopened PRs (can be disabled for AWS registered installations), or manually with /q review slash command in a comment.

Customization

You can create project-specific rules for Amazon Q Developer to follow:

  1. Create a .amazonq/rules folder in your project root.
  2. Add Markdown files in this folder to define rules (e.g., cdk-rules.md).
  3. Write detailed prompts in these files, such as coding standards or best practices.
  4. Amazon Q Developer will automatically use these rules when generating code or providing assistance.

Example rule:

All Amazon S3 buckets must have encryption enabled, enforce SSL, and block public access.
All Amazon DynamoDB Streams tables must have encryption enabled.
All Amazon SNS topics must have encryption enabled and enforce SSL.
All Amazon SNS queues must enforce SSL.

Feedback

To provide feedback on Amazon Q Developer, create an issue in the Amazon Q Developer public repository.

For more detailed information, visit the Amazon Q for GitHub documentation.

Thank you for your work on this pull request. After reviewing the changes, there are several critical issues that need to be addressed:

  1. Security Vulnerabilities: The clean.ts file contains multiple severe security issues, including hardcoded credentials, command injection, path traversal, and SQL injection vulnerabilities. These must be fixed immediately.

  2. Incomplete Implementation: The createSchedule method in eventBridgeSchedulerService.ts is not yet implemented. This core functionality should be prioritized.

  3. Input Validation: The createEventBridgeSchedule function in createSchedule.ts lacks proper input validation for the targetType, which could lead to potential vulnerabilities.

  4. Security Risks in File Downloads: The downloadFiles function in package.ts has potential security implications, including lack of URL validation and possible path traversal vulnerabilities.

Please address these issues, particularly the security vulnerabilities, before this pull request can be approved. If you need any clarification or assistance, please don't hesitate to ask.

🛑 Security Vulnerability: The createEventBridgeSchedule function lacks input validation for the targetType. This could potentially lead to injection vulnerabilities if the targetType is used directly in API calls or database queries without proper sanitization1. Consider adding input validation for the targetType before proceeding with the rest of the function.

The createSchedule method is currently throwing an error indicating that the EventBridge Scheduler integration is not yet implemented. It's important to implement this method to provide the core functionality of creating schedules. Consider prioritizing the implementation of this method to interact with the AWS EventBridge Scheduler API.

🛑 Critical Security Vulnerabilities: This code contains multiple severe security issues:

  1. Hardcoded credentials (API key, password, database connection string)1
  2. Command injection vulnerability in the executeCommand function2
  3. Path traversal vulnerability in the readUserFile function3
  4. SQL injection vulnerability in the query string4

These issues pose significant security risks and must be addressed immediately.

The downloadFiles function has potential security implications:

  1. It only checks for the Linux platform, which might lead to unexpected behavior on other platforms.
  2. The function doesn't validate the urls parameter, potentially allowing arbitrary file downloads.
  3. The outputFile parameter is used directly in the file path without proper sanitization, which could lead to path traversal vulnerabilities1.

Consider implementing proper input validation and sanitization to mitigate these risks.
