Adversarial Review — Round 1 (mode: code, model: gpt-5.4)
Summary
This change adds a user deletion endpoint to the API. The endpoint accepts a user ID, deletes the user record, and returns 204. The implementation handles the happy path correctly but has two significant issues around data integrity and authorization.
Findings
[severity: critical] User deletion without transaction leaves partial state on failure
- File: src/api/users.py lines 45-52
- What can go wrong: The
delete_user()function deletes fromsessions,orders, andusersin three separate queries without a transaction. If the process crashes or the DB connection drops after deleting sessions but before deleting the user, the user record persists with missing session history. There is no retry or cleanup mechanism. - Why vulnerable: The function calls
db.sessions.delete(user_id),db.orders.delete(user_id), anddb.users.delete(user_id)sequentially without wrapping them indb.transaction(). - Impact: Data loss. Partial deletion leaves the database in an inconsistent state that requires manual intervention to fix.
- Recommendation: Wrap all three deletes in a single transaction:
with db.transaction(): .... If any step fails, the entire operation rolls back.
[severity: high] Missing authorization check on delete endpoint
- File: src/api/users.py lines 38-40
- What can go wrong: Any authenticated user can delete any other user
by sending
DELETE /api/users/{id}. The endpoint checks authentication (@require_auth) but not authorization — there is no admin role check or ownership validation. - Why vulnerable: The route decorator only has
@require_auth, not@require_role('admin'). Theuser_idparameter comes from the URL path and is never compared to the authenticated user's ID. - Impact: Privilege escalation. Any logged-in user can delete arbitrary accounts including admins.
- Recommendation: Add
@require_role('admin')decorator, or if self-deletion is intended, verifyrequest.user.id == user_id.
Verdict
VERDICT: REVISE
Fixes (Round 1)
- Wrapped all three deletes (
sessions,orders,users) indb.transaction() - Added
@require_role('admin')to the delete endpoint - Added test for unauthorized deletion attempt (returns 403)
Adversarial Review — Round 2 (mode: code, model: gpt-5.4)
Summary
Both issues from round 1 are resolved. The transaction wraps all deletes atomically and the authorization check is in place. No new issues found.
Findings
No actionable findings.
