Quick Summary

Goal: Deliver a read-only security audit that surfaces every exploitable vulnerability — OWASP Top 10 (2021), microservices/API boundaries, auth flows, input validation, message-bus trust, dependency CVEs — as a structured plans/reports/ report where each finding carries file:line evidence, a traced data flow to sink, severity, and concrete remediation, so the team can fix the real risks first.

Summary:

• BLOCKING order: Phase 1 detect tech stack → Phase 2 research CVEs/attack classes per stack → Phase 3 evaluate; produce NO finding before Phase 2 completes (wrong stack = wrong patterns = false confidence).
• Read-only: NEVER modify source; every finding needs file:line + traced data flow to sink + reproduction — pattern match alone is not a finding.
• Write findings to plans/reports/ after each section (never batch); redact secrets with [REDACTED]; identity/TenantId must come from JWT claims, never the request body.

Audit Workflow:

1. Scope — Identify services/features; read project reference docs; map entry points (HTTP, message consumers, scheduled jobs)
2. Threat Model — Per entry point, identify trust boundaries, data flows, and asset sensitivity BEFORE code diving
3. OWASP A01–A10 — Systematic pass (checklist below)
4. Microservices Boundary — JWT propagation, message-bus validation, service-to-service trust
5. Auth & AuthZ Deep Dive — Trace identity source → JWT → permission provider → resource gate
6. Dependency CVE Scan — Run the ecosystem scanner for each detected package manager
7. Secrets & Config — Hardcoded secrets, config exposure, key rotation
8. Report — Structured findings to plans/reports/ with severity, evidence, CVSS estimate, remediation

Severity Scale:

Level	Definition	SLA
Critical	Exploitable now, no auth required, direct data/RCE impact	Immediate
High	Exploitable with low effort or after auth, significant impact	48h
Medium	Defense gap, requires chaining or privilege	1 sprint
Low	Hardening opportunity, defense-in-depth	Backlog
Info	Observation, no direct risk	—

Key Rules:

• NEVER modify source code — read-only audit only
• Every finding MUST include file:line, a data-flow trace, and reproduction steps
• NEVER report a finding without traced code-path evidence — pattern matching alone is not a finding
• NEVER expose credentials/secrets/tokens in reports — redact with [REDACTED]

[CRITICAL] Read-only audit — NEVER modify source code. Produce reports and recommendations only. Evidence Gate — Every finding carries file:line proof + confidence % (>80% report; <80% mark "unverified / needs manual review"). NEVER fabricate file paths, function names, or behavior — why: a hallucinated vuln wastes a remediation cycle and erodes trust in the audit. Report First — Write findings to plans/reports/ after each section; never batch at end — why: context exhaustion mid-audit silently loses all unwritten findings. False-Positive Discipline — Per potential finding: trace full code path, confirm tainted data reaches the sink, verify no upstream validation neutralizes risk BEFORE reporting — why: pattern match alone is not a finding.
