# Security Review: Dependency & Supply Chain Security

**Date**: September 11, 2025
**Scope**: MindRoom project dependency and supply chain security assessment
**Reviewer**: Security Analysis System

## Executive Summary

This report presents a comprehensive security review of dependency and supply chain security for the MindRoom project. The assessment covers 5 critical checklist items focusing on dependency vulnerabilities, Docker base image security, source verification, version pinning, and automated scanning implementation.

### Overall Security Posture (Sept 17, 2025): **MEDIUM**
- ✅ Python (`pip-audit`) clean as of Sept 17
- ⚠️ Frontend `pnpm audit` shows 5 open vulns (esbuild/mermaid/vite) – dev tooling but should be patched
- ✅ Dependencies sourced via official registries with lock files
- ❌ No automated vulnerability scanning in CI/CD yet (manual runs only)

### 2. Docker Base Image Security ✅ PASS

**Images Analyzed:**
1. `ghcr.io/astral-sh/uv:latest` - Official UV package manager
2. `public.ecr.aws/docker/library/python:3.13-slim` - Official Python slim
3. `public.ecr.aws/docker/library/node:20-slim` - Official Node.js slim
4. `public.ecr.aws/docker/library/node:20-alpine` - Official Node.js Alpine
5. `public.ecr.aws/nginx/nginx:alpine` - Official Nginx Alpine

**Assessment Results:**
- ✅ All images from official/trusted sources
- ✅ Using slim/alpine variants (reduced attack surface)
- ✅ Using public ECR to avoid Docker Hub rate limits
- ⚠️ Some images use `:latest` tag (should use specific versions)
- ✅ Multi-stage builds properly implemented
- ✅ No unnecessary tools in production images

**Security Recommendations:**
1. Pin specific image versions instead of `:latest`
2. Consider using distroless images for production
3. Regular base image updates in CI/CD

### 3. Dependency Source Verification ✅ PASS

**Python Dependencies:**
- ✅ All from official PyPI: `https://pypi.org/simple`
- ✅ SHA256 hashes verified in uv.lock
- ✅ No private or unofficial registries detected
- ✅ No Git dependencies from untrusted sources

**Node.js Dependencies:**
- ✅ All from official npm registry
- ✅ Package integrity verified via pnpm-lock.yaml
- ✅ No private registries or Git dependencies
- ✅ Official @radix-ui, @lobehub, and framework packages

**Third-party Services:**
- ✅ All external tools from verified publishers
- ✅ Anthropic, OpenAI, Google - official SDKs
- ✅ Cloud services from official providers

### 4. Dependency Version Pinning ✅ PASS

**Python (uv.lock):**
- ✅ **Excellent**: Exact version pinning with hashes
- ✅ All 400+ dependencies locked to specific versions
- ✅ SHA256 integrity hashes for all packages
- ✅ Resolution markers for Python version compatibility

Example:
```toml
[[package]]
name = "agentql"
version = "1.13.0"
source = { registry = "https://pypi.org/simple" }
sdist = { hash = "sha256:e80b3f02a047421be8939e278a168503576a612f6c9e75eb198459895b1e359e" }
```

**Node.js (pnpm-lock.yaml):**
- ✅ **Excellent**: Exact version pinning
- ✅ All 1,148+ dependencies locked to specific versions
- ✅ Nested dependency resolution locked
- ✅ Package integrity verification

**pyproject.toml Analysis:**
- ✅ Appropriate version constraints (e.g., `>=2.40.3`)
- ✅ Critical packages with minimum versions specified
- ✅ Compatible version ranges, not overly restrictive

**Supply Chain Attack Prevention:**
- ✅ Lock files prevent unexpected updates
- ✅ Hash verification prevents package tampering
- ✅ Reproducible builds enabled
- ✅ No floating version dependencies

### 5. Automated Vulnerability Scanning ❌ FAIL

**CI/CD Pipeline Assessment:**
- ❌ **No GitHub Actions workflows found**
- ❌ **No automated dependency scanning**
- ❌ **No vulnerability monitoring**
- ❌ **No automated security updates**
