description: Scan lỗ hổng NuGet + npm cho SOLUTION_ERP (.NET 10 + 2 FE React). Chạy dotnet list package --vulnerable + npm audit cho fe-admin/fe-user, report CVE + decide upgrade path. Respect pin constraint (MediatR 12.4.1 cannot upgrade to 14, Swashbuckle 6.9.0 cannot upgrade to 7+, Node 20.x only for CI).
when-to-use:
  - "dependency audit"
  - "npm audit"
  - "dotnet vulnerable"
  - "scan CVE"
  - "nâng cấp package"
  - "security dependencies"
  - "deps scan CI"

# Dependency Audit — SOLUTION_ERP

> **Context:** Phase 5.1 security backlog explicit — "Dependencies scan CI (`dotnet list package --vulnerable --include-transitive`, `npm audit --audit-level=high`)". Chưa hook vào workflow, có thể chạy manual.

## Commands (chạy từ root repo)

### Backend .NET

```powershell
# Restore trước khi scan (first time / sau pull)
dotnet restore

# Scan top-level + transitive vulnerable
dotnet list src/Backend/SolutionErp.Api/SolutionErp.Api.csproj package --vulnerable --include-transitive

# Scan cả solution
dotnet list SolutionErp.slnx package --vulnerable --include-transitive

# Outdated check (khác vulnerable — chỉ cảnh báo version cũ)
dotnet list SolutionErp.slnx package --outdated
```

**Output interpretation:**
- `> High` / `> Critical` severity → fix ngay (pin lên patch/minor version không breaking)
- `> Moderate` → plan trong sprint tới
- `> Low` → track, không rush

### Frontend 2 app

```powershell
# fe-admin
cd fe-admin
npm audit --audit-level=high
npm audit --json > ../tmp/fe-admin-audit.json  # detail
cd ..

# fe-user
cd fe-user
npm audit --audit-level=high
npm audit --json > ../tmp/fe-user-audit.json
cd ..
```

Hoặc chạy song song từ 1 lệnh:
```powershell
cd fe-admin; npm audit --audit-level=high; cd ..; cd fe-user; npm audit --audit-level=high; cd ..
```

## ⚠️ Pin constraints — KHÔNG auto-upgrade dù có CVE/outdated

Đọc `docs/gotchas.md` trước khi bấm `npm audit fix` hoặc `dotnet add package`. Những pin sau đây có lý do rõ ràng:

### Backend pins

| Package | Current | Lý do không upgrade | Gotcha # |
|---|---|---|---|
| `MediatR` | **12.4.1** | v14 breaking — `AddMediatR` fail resolve `IMediator` | #1 |
| `Swashbuckle.AspNetCore` | **6.9.0** | v10+ yêu cầu `Microsoft.OpenApi` 2.x — breaking `Swashbuckle.AspNetCore.Models` namespace | #2 |
| `Microsoft.AspNetCore.OpenApi` | **removed** | Conflict Swashbuckle, dùng riêng 1 trong 2 | #2 |
| `Microsoft.EntityFrameworkCore` | **10.x** | Pin theo .NET 10 SDK (`global.json` 10.0.104) | — |
| `Microsoft.AspNetCore.Identity` | **10.x** | Pin theo .NET 10 — `AddIdentityCore` không có `AddDefaultTokenProviders` | #8 |

### Frontend pins

| Package | Current | Lý do pin |
|---|---|---|
| `typescript` | **6.x** | `erasableSyntaxOnly` cấm enum → đã rewrite const-object pattern, rollback = rewrite lại (#3) |
| `vite` | **8.x** | rolldown native binding cần fresh `node_modules` trên CI (gotcha npm ci fail) |
| `@microsoft/signalr` | **8.0.7** | SignalR hub version parity với ASP.NET Core 10 — test kỹ trước khi bump |
| `react` | **19** | Auto-scaffolded, đã style-adapt cho |
| Node engine | **`>=20`** | CI pin `20.x` qua `.nvmrc` (NamGroup bài học, gotcha #5) |

## Workflow khi fix vulnerability

```
1. Đọc CVE detail: npm audit (--json) hoặc https://github.com/advisories/GHSA-xxxx
2. Check có phải transitive dep không?
   - Direct → bump trong package.json / .csproj, test build
   - Transitive → check ancestor package, có newer không
3. Nếu ancestor fix available nhưng là major version:
   - Đánh giá breaking change (đọc CHANGELOG)
   - Nếu yes → defer + document, dùng npm overrides hoặc dotnet transitive constraint
4. Test local:
   - BE: dotnet build + dotnet run → /health/ready healthy
   - FE: npm run build + npm run dev → login flow + CRUD smoke test
5. Commit [CLAUDE] Infra: bump <package> for CVE-xxxx
6. Watch CI xanh
```

## CI integration (TODO — Phase 5.1 backlog)

Dự kiến thêm vào `.gitea/workflows/deploy.yml` step:

```yaml
- name: Deps audit
  shell: pwsh
  run: |
    dotnet list SolutionErp.slnx package --vulnerable --include-transitive 2>&1 | Tee-Object -Variable nugetOut
    if ($nugetOut -match 'has the following vulnerable packages') {
      Write-Error "NuGet vulnerabilities found"
      exit 1
    }
    cd fe-admin; npm audit --audit-level=high; if ($LASTEXITCODE -ne 0) { exit 1 }; cd ..
    cd fe-user;  npm audit --audit-level=high; if ($LASTEXITCODE -ne 0) { exit 1 }; cd ..
```

Gate nên set `continue-on-error: true` lần đầu → monitor 1 tuần → enable blocking.

## Output template (khi manual chạy)

```markdown
# Deps audit — {YYYY-MM-DD}

## NuGet
- Critical: 0
- High: 0
- Moderate: 0
- Low: 0

## npm fe-admin
- Critical: 0
- High: 0
- Moderate: N (liệt kê)

## npm fe-user
- Critical: 0
- High: 0
- ...

## Action items
- [ ] Bump X from a.b.c → a.b.d (patch, safe) — CVE-xxxx
- [ ] Defer Y (v3 → v4 breaking, plan Phase N)
- [ ] Override Z via npm overrides (transitive, no direct bump)
```

Lưu vào `docs/changelog/deps-audit-{YYYY-MM-DD}.md` nếu có action.
