feat: refactor authentication middleware and add OAuth2 support

Opendev-arjun wants to merge 14 commits into main

Changes requested

Reviewed 14 commits across 6 files. Found 1 critical issue, 1 security concern, and 1 performance improvement.

Criticalsrc/auth/session.ts:47

Null dereference on unauthenticated request

user.profile is accessed without verifying the session state. If the request originates outside an authenticated context, this will throw at runtime.

Fix: Add a guard: if (!user?.profile) return null before line 47.

Securityapi/payments/webhook.ts:112

Signature verification bypass possible

The HMAC comparison on line 112 uses a timing-unsafe string equality check. A timing attack could allow forged webhook payloads to pass validation.

Fix: Replace with crypto.timingSafeEqual() for constant-time comparison.

Performancecomponents/UserList.tsx:34

N+1 query pattern inside render loop

getUser() is called on every iteration of the forEach starting at line 34. With 100 users this creates 100 sequential DB queries.

Fix: Batch fetch all users upfront with getUsers(ids), then use a Map for O(1) lookup.

Automated PR Analysis

Every pull request is automatically reviewed within 60 seconds of creation. Zero configuration, zero friction in your existing workflow.

Deep Bug Detection

Identifies null reference errors, logic flaws, edge cases, and off-by-one errors that escape static linters and human reviewers.

Security Scanning

Performance Insights

Surfaces N+1 queries, memory leaks, inefficient loops, and unnecessary re-renders before they reach your production environment.

Repository Analytics

Track code quality trends, developer velocity, issue recurrence, and review turnaround across your entire codebase over time.
