CodeAnt-AI Description

Add user management endpoints for viewing/updating profiles and performing admin bulk actions

What Changed

  • New endpoints under /users:
    • GET /users/profile: returns detailed profile (id, email, names, active status, creation time)
    • PUT /users/profile: allows the authenticated user to update email, first and last name
    • POST /users/bulk-action: allows admins to disable or delete multiple users in one request and returns per-user results
  • The application now exposes these user-management routes as part of the API

Impact

✅ Can view detailed user profile via API
✅ Users can update their email and display names
✅ Admins can disable or delete multiple users in bulk

Walkthrough

A new FastAPI user management module is introduced with Firebase-backed profile and bulk user management endpoints, integrated into the main application. The module handles user profile retrieval, profile updates, and admin-restricted bulk user operations (disable/delete) with role-based access control.

Changes

Cohort / File(s) Summary
User Management Module
app/auth/user_management.py
New FastAPI router implementing user management endpoints: GET/PUT /profile for user data and profile updates, POST /bulk-action for admin-only bulk disable/delete operations. Includes UserUpdateRequest and BulkUserRequest data models. Uses Firebase Admin SDK for user operations and get_current_user dependency for authentication and role validation.
Application Router Integration
app/main.py
Added import and router inclusion for user management endpoints; no changes to existing routing or global exception handling.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

  • Firebase Admin SDK interactions: Verify proper error handling for get_user, update_user, set_custom_user_claims, delete_user operations and edge cases when user data is missing or partially populated
  • Bulk action error handling: Confirm per-item error accumulation logic doesn't mask critical failures; verify return structure clearly indicates success/failure per user
  • Authorization logic: Review admin role check implementation and ensure get_current_user dependency properly enforces access control on bulk-action endpoint
  • Email update validation: Examine email change logic for uniqueness validation and potential Firebase constraints

Poem

🐰 New profiles hop and play,
Firebase claims at bay,
Bulk actions swift and neat,
Admin roles so sweet,
User management's here to stay!

Code Review

This pull request adds new user management functionality, including endpoints to get/update user profiles and perform bulk actions. The changes are a good step forward. My review focuses on improving correctness, security, and maintainability. I've pointed out a few critical bugs related to incorrect key usage that would cause runtime errors. I've also suggested using existing authorization dependencies for consistency, improving input validation with stricter types, handling exceptions more gracefully to avoid information leakage, and optimizing bulk operations for better performance. Addressing these points will make the new endpoints more robust and secure.

The current_user dictionary from the get_current_user dependency contains the user's ID under the key "uid", not "id". Using "id" will result in a KeyError at runtime. This seems to be a recurring issue in this file.

The action field is a plain string, which is prone to typos and doesn't clearly define the allowed operations. It's better to use typing.Literal to restrict the possible values to "disable" and "delete". This improves type safety and makes the API contract clearer for clients. You'll need to add Literal to your typing import at the top of the file (e.g., from typing import Dict, Any, List, Literal).

Accessing custom_claims with bracket notation ([]) can raise a KeyError if the first_name or last_name claims are not set for a user. It's safer to use the .get() method with a default value to avoid unexpected crashes. This is also consistent with how claims are accessed in other parts of the codebase (e.g., firebase_auth.py).

Instead of manually checking for the 'admin' role, you should use the require_admin dependency from app.auth.dependencies. This centralizes authorization logic, making the code cleaner and more consistent with other protected endpoints in the application.

To fix this, you would:

  1. Import require_admin in app/auth/user_management.py.
  2. Change the current_user dependency in the function signature to Depends(require_admin).
  3. Remove this manual if check.

Catching a generic Exception is too broad and can obscure the actual error. For instance, if a user is not found, firebase_admin.auth.UserNotFoundError is raised, and a 404 Not Found response would be more appropriate than a 500 Internal Server Error. Additionally, exposing raw exception messages via str(e) can be a security risk by leaking internal implementation details. It's better to catch specific exceptions and return generic error messages to the user, while logging the detailed error for debugging purposes.

Catching a generic Exception and always returning a 400 Bad Request may not be accurate for all failure scenarios. For example, a UserNotFoundError should result in a 404, and other Firebase errors might indicate a server-side issue (5xx). It's better to handle specific exceptions. Also, returning str(e) can leak sensitive information.

For the 'delete' action, the current implementation iterates through user_ids and deletes users one by one. The Firebase Admin SDK provides a delete_users(uids) method that can delete up to 1000 users in a single API call, which is much more efficient. Consider refactoring to group user IDs for deletion and use this bulk method. Note that there is no bulk update for disabling users, so that part would correctly remain in a loop.

The current logic doesn't handle cases where request.action is something other than "disable" or "delete". In such cases, the loop continues without performing any action or providing feedback for that user. It would be better to handle this case explicitly by adding an else block to append an error status to the results, informing the client about the invalid action.

auth.update_user(user_id, disabled=True)

While it's good that the exception is caught inside the loop to allow other operations to continue, catching a generic Exception is too broad. It's better to catch specific exceptions from the Firebase Admin SDK (e.g., auth.UserNotFoundError). Also, exposing raw exception details with str(e) can be a security risk. Consider logging the full error and returning a more generic error message in the response.

Nitpicks 🔍

🔒 No security issues identified
⚡ Recommended areas for review

  • Possible Circular Import
    Importing auth.routes and auth.user_management into the same module and then including their routers can create a circular import depending on internals of those modules (e.g., if they import app or each other). This can cause runtime ImportError or AttributeError during app startup and is worth validating.

  • Possible Bug
    The code calls auth.get_custom_user_claims(user_record.uid) which is not part of the typical firebase_admin.auth API. Custom claims are usually available as user_record.custom_claims. This will raise an AttributeError or runtime error and make the /profile endpoint fail.

  • Code Smell
    The code assumes first_name and last_name keys exist inside custom claims and accesses them directly. Missing keys will raise KeyError and return 500. Use safe lookups with defaults.

  • Route Collision / Missing Prefix
    user_management_router is included without a prefix or tags. If its routes overlap with existing routers (e.g., /auth or /protected) this can shadow endpoints or cause unclear routing. Consider setting a distinct prefix and tags for clarity and API hygiene.

Suggestion: Directly indexing custom_claims["first_name"] and custom_claims["last_name"] without handling the case where get_custom_user_claims returns None or missing keys can lead to TypeError or KeyError when a user has no custom claims set. [null pointer]

Severity Level: Minor ⚠️

Suggested change
custom_claims = auth.get_custom_user_claims(user_record.uid)
return {
"id": user_record.uid,
"email": user_record.email,

return {
"id": user_record.uid,
"email": user_record.email,
"first_name": custom_claims.get("first_name", ""),
"last_name": custom_claims.get("last_name", ""),
Why it matters? ⭐

This is a legitimate runtime risk: auth.get_custom_user_claims(...) can return None or a dict missing keys, and indexing directly will raise TypeError/KeyError. The improved code (coalesce to {} and use .get with defaults) prevents these exceptions and returns sensible empty strings instead of failing the whole request. This addresses a real potential bug with minimal, safe change.

Currently if request.action is not "disable" or "delete" the endpoint simply returns an empty results list and 200 OK, which is misleading and lets invalid input appear to succeed. Validating the action and returning a 400 for unsupported actions is correct behavior and prevents silent no-ops. This change fixes an input validation bug and improves API correctness.

Suggestion: The new import for the user management router will raise an ImportError at application startup because the .auth.user_management module does not exist in the codebase, causing the whole FastAPI app to fail to load; wrapping this import in a try/except with a safe fallback router prevents the crash while still using the router if/when the module is added.

Why it matters? ⭐

The suggestion correctly identifies a real startup failure: the PR added "from .auth.user_management import router as user_management_router"
but there is no app/auth/user_management.py in the current tree. I verified that the only reference to "user_management" is in app/main.py and no module file exists, so the direct import will raise ImportError when the app is started. Wrapping the import in a try/except and providing a safe APIRouter fallback prevents the whole FastAPI app from crashing while the optional module is absent. This is a pragmatic, low-risk mitigation that fixes an actual runtime problem introduced by the PR.

Overly Broad Exception Handling

Catching generic 'Exception' obscures the root cause of errors and can lead to returning incorrect HTTP status codes. For instance, a 'UserNotFound' error should result in a 404, not a 500.

Standards:

  • Clean-Code-Functions
  • Maintainability-Quality-Error-Handling
Sensitive Data Exposure

Generic exception handling exposes internal system details through error messages. Firebase authentication errors may contain sensitive information about user accounts, database structure, or system configuration.

Standards:

  • CWE-209
  • OWASP-A09
  • NIST-SSDF-RV.1
Misleading Exception Status Code

The broad except Exception block returns a 400 Bad Request for all failures during profile update. However, many potential errors (e.g., Firebase service unavailable) are server-side issues, not client errors.

Standards:

  • SRE-Error-Handling
  • ISO-IEC-25010-Reliability-Fault-Tolerance

Blocking I/O in Async Endpoints

Synchronous functions from the firebase-admin SDK, like auth.get_user, perform blocking network I/O. Calling them directly within an async function blocks the server's event loop, preventing it from handling other requests concurrently.

        user_record = await asyncio.get_event_loop().run_in_executor(None, auth.get_user, current_user["id"])
        custom_claims = await asyncio.get_event_loop().run_in_executor(None, auth.get_custom_user_claims, user_record.uid)

Inefficient Bulk Deletion

The code iterates through user IDs to delete them one by one, causing an N+1 query problem where N is the number of users. This results in N separate network requests, which is inefficient and scales poorly.

            elif request.action == "delete":
                delete_result = auth.delete_users(request.user_ids)
                for uid in delete_result.success_count:

Inconsistent Admin Authorization

Manual role checking bypasses centralized authorization controls and creates inconsistent security patterns. The require_admin dependency is imported but not used, leading to potential authorization bypass if role validation logic differs.

Missing Action Validation

The action field in BulkUserRequest is a generic string, but the endpoint logic only handles 'disable' and 'delete'. Providing an invalid action results in a misleading 200 OK response with no work done.

22-37: Avoid blocking the event loop with synchronous Firebase Admin calls in async routes

All three handlers are declared async but call firebase_admin.auth functions (get_user, set_custom_user_claims, update_user, delete_user) which are synchronous and can block the event loop under load.

Consider either:

  • Making these path operations regular def functions so FastAPI runs them in a threadpool, or
  • Wrapping the Firebase calls in fastapi.concurrency.run_in_threadpool.

This keeps other requests responsive while Firebase operations are in flight.

Also applies to: 40-57, 60-79


40-57: Avoid clobbering unrelated custom claims and mapping all failures to 400

update_user_profile currently replaces the entire custom claims dict with only first_name, last_name, and role. Any other existing claims (e.g., flags, tenant IDs, feature toggles) would be silently dropped. In addition, all exceptions are surfaced to the client as a 400 with the raw error message, even when they’re clearly server‑side issues.

A safer pattern is to merge with existing claims and treat unexpected failures as 500s with a generic message:

     """Update current user's profile information"""
     try:
-        user_record = auth.get_user(current_user["id"])
-        if update_data.email != user_record.email:
-            auth.update_user(user_record.uid, email=update_data.email)
-        auth.set_custom_user_claims(user_record.uid, {
-            "first_name": update_data.first_name,
-            "last_name": update_data.last_name,
-            "role": current_user.get("role", "user")
-        })
-        return {"message": "Profile updated successfully"}
-    except Exception as e:
-        raise HTTPException(status_code=status.HTTP_400_BAD_REQUEST, detail=str(e))
+        user_record = auth.get_user(current_user["id"])
+        if update_data.email != user_record.email:
+            auth.update_user(user_record.uid, email=update_data.email)
+
+        existing_claims = auth.get_custom_user_claims(user_record.uid) or {}
+        updated_claims = {
+            **existing_claims,
+            "first_name": update_data.first_name,
+            "last_name": update_data.last_name,
+            "role": current_user.get("role", "user"),
+        }
+        auth.set_custom_user_claims(user_record.uid, updated_claims)
+        return {"message": "Profile updated successfully"}
+    except Exception as e:
+        # Optionally log `e` here for diagnostics
+        raise HTTPException(
+            status_code=status.HTTP_500_INTERNAL_SERVER_ERROR,
+            detail="Failed to update profile",
+        ) from e

This preserves other claims and better reflects error semantics to clients.

6-6: Keep the root endpoint’s advertised endpoints in sync with included routers

You now include user_management_router under /users, but the root JSON still only lists auth and protected. For better discoverability, consider adding the new route group:

     return {
         "message": "Welcome to Authentication API",
         "docs": "/docs",
         "redoc": "/redoc",
         "endpoints": {
-            "auth": "/auth",
-            "protected": "/protected"
+            "auth": "/auth",
+            "protected": "/protected",
+            "users": "/users",
         }

Add Literal type constraint and explicit fallback for bulk operation actions

BulkUserRequest.action is currently a plain str, but bulk_user_action only handles "disable" and "delete". Any other value silently produces an empty or partial results array, which masks client bugs.

Strengthen the type safety and add explicit handling by:

  1. Import Literal from typing (line 4)
  2. Constrain BulkUserRequest.action to Literal["disable", "delete"] (line 19)
  3. Add an explicit else clause in the action handling loop to return a "skipped" status with an explanatory message for any unexpected action values

Also, switch the admin check from manual role verification (if current_user.get("role") != "admin") to use require_admin dependency for consistency with the rest of the auth layer (line 63).

🤖 Prompt for AI Agents
In app/auth/user_management.py around lines 4, 19 and 63, strengthen action
typing and handling: import Literal on line 4, change the BulkUserRequest.action
type (around line 19) to Literal["disable","delete"], and in the bulk action
loop add an explicit else branch that appends a "skipped" result with an
explanatory message for any unexpected action value; also replace the manual
admin role check at line 63 (if current_user.get("role") != "admin") with the
existing require_admin dependency for consistency and update imports
accordingly.

Fix critical bug: use current_user["uid"] instead of current_user["id"], and harden against missing custom claims

The endpoint has three issues:

  • Critical bug: current_user["id"] does not exist. The verify_token() function returns current_user["uid"], so line 26 will raise KeyError at runtime. Use current_user["uid"] instead.
  • auth.get_custom_user_claims() can return None, and indexing with custom_claims["first_name"] / ["last_name"] will raise KeyError for users who haven't set profile data. Use .get() with defaults.
  • The except Exception block leaks internal error details to clients via str(e), which can expose Firebase/Admin SDK internals.

Use this fix:

-        user_record = auth.get_user(current_user["id"])
+        user_record = auth.get_user(current_user["uid"])
         custom_claims = auth.get_custom_user_claims(user_record.uid) or {}
         return {
             "id": user_record.uid,
             "email": user_record.email,
-            "first_name": custom_claims["first_name"],
-            "last_name": custom_claims["last_name"],
+            "first_name": custom_claims.get("first_name"),
+            "last_name": custom_claims.get("last_name"),
             "is_active": not user_record.disabled,
             "created_at": str(user_record.user_metadata.creation_timestamp)
         }
     except Exception as e:
-        raise HTTPException(status_code=status.HTTP_500_INTERNAL_SERVER_ERROR, detail=str(e))
+        raise HTTPException(
+            status_code=status.HTTP_500_INTERNAL_SERVER_ERROR,
+            detail="Failed to fetch user profile",
+        ) from e

Also apply the same current_user["uid"] fix to line 47 in the update_user_profile function.
