Summary of Changes

Hello @0xi4o, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the application's security posture by implementing robust access control mechanisms. It introduces new middleware functions to validate user and organization-level permissions for data access, ensuring that users can only retrieve data they are authorized to see. Additionally, several account-related API endpoints have been updated to prevent the unnecessary exposure of sensitive user information in their responses, returning only a success confirmation.

Highlights

• New Access Control Middleware: Introduced checkUserIdMatch middleware in IdentityManager to ensure users can only access their own data unless specific organization permissions apply.
• Organization-Level Access Control: Implemented checkOrganizationUserAccess middleware in IdentityManager to enforce organization-level access control, verifying user permissions and organization membership for data requests.
• Route Security Enhancement: Applied new access control middlewares to GET routes for /user, /organization-user, and /workspace-user to secure data retrieval.
• Reduced Data Exposure: Modified AccountService methods (createAccount, updateAccount, updateAccountPassword) to return a generic success message instead of sensitive user details, reducing data exposure.

Code Review

This pull request aims to enhance security by adding authorization middleware to several endpoints and reducing unnecessary data exposure. The introduction of checkUserIdMatch and checkOrganizationUserAccess middleware is a positive step towards securing user data. However, my review has identified a critical security vulnerability where the new checks can be bypassed, a potential privilege escalation issue due to overly permissive access control, and a minor inconsistency in error handling. The changes to reduce data returned from account management endpoints are a welcome improvement for security.
