PRD: JWT Token Support for Webhook Triggers

Overview

This Product Requirements Document (PRD) details the addition of JWT (JSON Web Token) token support for webhook triggers in the MeshHook project. This feature is a critical enhancement for Phase 5: Webhook System, aimed at bolstering security by enabling the verification of JWT tokens for incoming webhook requests. This aligns with MeshHook's overarching goals of providing a secure, scalable, and user-friendly workflow automation platform. JWT token support will ensure that only authenticated and authorized requests trigger workflows, enhancing the security posture of the MeshHook platform.

Functional Requirements

1. JWT Verification: The system must be able to verify the JWT attached to incoming webhook requests to authenticate and authorize these requests.
2. Configurable JWT Secrets: Users must be able to configure JWT secret keys and expected claims through both a UI and an API endpoint for each webhook trigger in their project.
3. Dynamic Secret Fetching: The system should support dynamic fetching of JWT secrets from the project's secrets vault, allowing secrets to be updated without redeploying or restarting services.
4. Error Handling and Feedback: Clear, actionable error responses should be provided for verification failures, and these should be logged appropriately for auditing purposes.
5. User Interface for JWT Configuration: Implement a user-friendly interface within the existing project settings to allow users to configure JWT settings for webhook triggers.

Non-Functional Requirements

1. Performance: The JWT verification process must be optimized to ensure minimal impact on webhook processing latency.
2. Security: Implement secure storage and access mechanisms for JWT secrets and ensure robust validation of JWT signatures and claims to prevent security vulnerabilities.
3. Reliability: The webhook processing system, including JWT verification, should aim for 99.9% uptime.
4. Maintainability: The implementation should follow the project's existing coding standards, ensuring the code is clean, well-documented, and easy to maintain.

Technical Specifications

Architecture Context

• Integration Points:
  • The feature will be integrated into the SvelteKit frontend for configuration interfaces and the existing webhook processing pipeline for JWT verification.
  • Supabase Postgres will store JWT configuration settings.
• Technologies:
  • Use Node.js and a reputable JWT library for the verification process.
  • SvelteKit/Svelte 5 for frontend changes.
  • Supabase Realtime for logging.

Implementation Approach

1. Extend Webhook Configuration:
   • Update the webhook_triggers table schema to include a jwt_config JSONB column.
   • Design and implement UI changes in the SvelteKit frontend for JWT configuration.
2. Implement JWT Verification:
   • Integrate JWT verification into the webhook processing pipeline, ensuring the JWT is verified against the configured secret and claims before proceeding with the trigger.
   • Implement dynamic secret fetching logic, interfacing with the secrets vault as needed.
3. Logging and Monitoring:
   • Implement detailed logging for all verification attempts and outcomes.
   • Utilize Supabase Realtime to monitor these logs.

Data Model Changes

• webhook_triggers table will have a new jwt_config JSONB column to store JWT verification configurations, including secrets and claims.

API Endpoints

• New Endpoint: /api/v1/projects/{projectId}/webhooks/{webhookId}/jwt-config
  • Method: PUT
  • Body:

    {
      "secret": "string",
      "claims": {
        "iss": "example.com",
        "aud": "meshhook"
      }
    }

Acceptance Criteria

• JWT verification correctly authenticates and authorizes incoming requests for all configured webhook triggers.
• Users can configure JWT settings via both UI and API.
• Dynamic secret fetching is functional and tested.
• Unit and integration tests cover new functionality, maintaining a code coverage rate above 90%.
• Documentation is updated to reflect JWT configuration and verification processes.

Dependencies

• Access to a secure and maintained JWT library compatible with the project's Node.js version.
• Coordination with the frontend team for UI changes.

Implementation Notes

Development Guidelines

• Adhere to the project's existing coding conventions, utilizing ESLint and Prettier for code formatting.
• Follow Test-Driven Development (TDD) practices to ensure comprehensive test coverage from the outset.

Testing Strategy

• Unit Tests: Focus on isolated testing of JWT verification logic, configuration parsing, and dynamic secret fetching.
• Integration Tests: Ensure end-to-end testing of the webhook processing pipeline with JWT verification in place.
• Manual Testing: Conduct thorough manual testing of the UI and API for JWT configuration to ensure a seamless user experience.

Security Considerations

• Securely manage JWT secrets, ensuring they are only accessible to necessary components and are encrypted at rest.
• Thoroughly validate JWT signatures and claims to mitigate potential security threats.

Monitoring & Observability

• Implement detailed logging for all JWT verification attempts, capturing both successes and failures.
• Leverage Supabase Realtime for real-time monitoring of these logs, facilitating quick response to potential issues.
