# OWASP Top 10 Review (Cycle 9)

**Date**: 2026-06-25
**Framework**: OWASP Top 10:2021
**Scope**: Cycle-9 gRPC delta (AZ-1074/AZ-1075)

| Category | Status (cycle-9 delta) | Notes |
|----------|------------------------|-------|
| A01 — Broken Access Control | **PASS** | `[Authorize]` on gRPC service; anonymous calls rejected (integration tests cover JWT baseline) |
| A02 — Cryptographic Failures | **N/A** | TLS via Kestrel dev cert / production ingress — unchanged pattern from AZ-505 |
| A03 — Injection | **PASS** | No new string-built SQL; tile coords validated before expand |
| A04 — Insecure Design | **PASS (post-follow-up)** | F-AZ1074-1 unbounded collections **resolved** — caps aligned with REST |
| A05 — Security Misconfiguration | **PASS** | gRPC message size limits set; test compose no longer publishes DB port to host |
| A06 — Vulnerable Components | **PASS_WITH_WARNINGS** | New Grpc.AspNetCore 2.71.0 clean; D-AZ795-1 + D2-cy4 carry-overs |
| A07 — Auth Failures | **PASS** | Same JWT contract as REST; gRPC metadata `Authorization: Bearer` |
| A08 — Data Integrity Failures | **N/A** | No CI/CD or signing changes |
| A09 — Logging Failures | **PASS_WITH_WARNINGS** | F-AZ1074-2 **resolved**; F-AZ795-1/F-AZ795-2 REST carry-overs still open |
| A10 — SSRF | **N/A** | No URL inputs in gRPC contract |

## Verdict

**PASS_WITH_WARNINGS** cumulative (REST carry-overs). Cycle-9 delta: **PASS** after Step-14 follow-up fixes.
