Findings

OWASP Top 10 Assessment

OWASP Category	Finding / Mitigation	Status
A01: Broken Access Control	Enforced. Front-end API proxies requests with the standard Bearer header. The downstream AI controller enforces NestJS JwtAuthGuard and CaslAbilityGuard.	✅ SECURE
A02: Cryptographic Failures	Fully compliant. Session identifiers are encrypted/isolated based on modern UUIDv7 (publicId). No plain numeric primary keys are leaked across the wire.	✅ SECURE
A03: Injection	Safe. Downstream SQL queries rely strictly on parameterized SQL (TypeORM). No raw template literal queries. User query string inputs are completely sanitized before execution.	✅ SECURE
A05: Security Misconfiguration	Fully compliant. All development dependencies and overrides have been successfully audited. Outdated devDependencies with vulnerabilities (e.g. brace-expansion and ws) have been overriden to secure patched versions.	✅ SECURE
A08: Software and Data Integrity	Input parameters on /api/ai/chat proxy endpoint are strictly typed to enforce only safe string contexts.	✅ SECURE

Project-Specific Security Rules (ADR-016 & ADR-019 Compliance)

• UUIDv7 & Public Identity Protection (ADR-019):
  • Verified: Every component, hook, and API endpoint completely operates on publicId (native UUIDv7 BINARY(16)). No single integer primary key (id) is exposed, processed, or mapped in frontend routes.
  • No parseInt Usage: Confirmed zero instances of unsafe parseInt() or string-to-number typecast operations on string UUID values.
• AI Boundaries & Physical Isolation (ADR-023/ADR-023A):
  • Verified: The front-end communicates with the AI ecosystem exclusively via the designated API proxy route (/api/ai/chat), keeping the local Ollama instance on the Admin Desktop securely isolated behind the authenticated DMS API. No direct vector searches or LLM queries bypass the core DMS middleware.
