Security Review of Product Architecture: Identified Risks and Mitigations

Summary

This review identifies critical attack surfaces in the product architecture, prioritizes risks, and outlines actionable mitigations to secure the system while enabling safe deployment. Key risks include unvalidated rollback scripts, insecure API input validation, and third-party dependency vulnerabilities. Mitigations focus on automated validation, visibility tracking, and proactive remediation.

Key Risks and Mitigations

1. Unvalidated Rollback Scripts

Risk: Unvalidated rollback scripts expose data injection risks during reverts. Attackers could exploit schema mismatches to inject malicious payloads, corrupting state or exfiltrating data.
Severity: High
Mitigation Status: In progress
Action Items:

  • Implement SchemaCrawler for automated schema validation to detect mismatches.
  • Enforce CloudTrail logging for all rollback events to audit changes.
  • Add post-revert health checks:
    • Endpoint latency < 200ms.
    • Dependency conflict scans to detect incompatible libraries.

2. Insecure API Input Validation

Risk: Unfiltered user inputs allow injection attacks (SQLi, XSS, command injection), compromising backend systems or stealing data.
Severity: High
Mitigation Status: Not implemented
Action Items:

  • Enforce strict input validation rules across all API endpoints.
  • Use parameterized queries to prevent SQL injection.
  • Deploy WAF (Web Application Firewall) rules to block malicious patterns.

3. Third-Party Dependency Vulnerabilities

Risk: Unpatched libraries with known exploits (e.g., Log4j-style vulnerabilities) act as backdoors.
Severity: Critical
Mitigation Status: Partially addressed
Action Items:

  • Enforce SBOM (Software Bill of Materials) tracking for all dependencies.
  • Automate vulnerability scans (e.g., using tools like Snyk or Dependabot).
  • Build a dependency audit pipeline that blocks deployment of unmaintained components, not just logs them.

Disagreements and Resolutions

  • Technical Debt Remediation: Thaum and Chora emphasized that debt markers alone do not prevent exploitation—active remediation (not just visibility) is required. Subrosa’s initial focus on validation tools was补充 with prioritization of debt remediation.
  • SBOM Implementation: All parties agreed on SBOM tracking but diverged on enforcement. Chora advocated for blocking deployment of vulnerable dependencies, while Subrosa’s initial proposal focused on logging. The latter was adjusted to align with Chora’s stricter requirements.

Decisions and Next Steps

  1. Implement SchemaCrawler and CloudTrail: Complete by Q3 2026.
  2. Enforce Input Validation and WAF Rules: Integrated into CI/CD pipelines by Q3 2026.
  3. SBOM and Dependency Scans:
    • SBOM tracking enforced for all dependencies.
    • Automated scans integrated into deployment workflows.
    • Pipeline updated to block deployments with unresolved vulnerabilities.
  4. Technical Debt Remediation: Prioritize debt items with known exploits for Q3 remediation.

Outstanding Issues

  • Rollback Health Checks: Need to define latency thresholds and dependency scan tools.
  • WAF Rule Configuration: Requires collaboration with DevOps to tailor rules to API endpoints.
  • SBOM Tooling: Evaluate tools for SBOM generation (e.g., CycloneDX, SPDX).

Conclusion

The review confirms that while rollback scripts and API validation are critical to address, third-party dependencies pose the highest immediate risk. Mitigations are actionable and aligned with shipping priorities. All proposed fixes include clear paths to implementation, ensuring security does not block deployment.

Next Review: Q3 2026 — Validate implementation status of SchemaCrawler, WAF, and SBOM pipelines.
