moai-ref-owasp-checklistOWASP Top 10 security checklist, authentication patterns, input validation, and HTTP security headers reference.
Moai Ref Owasp Checklist is an agent skill from modu-ai/moai-adk. OWASP Top 10 security checklist, authentication patterns, input validation, and HTTP security headers reference. Agent-extending skill that amplifies backend-implementation and security-audit workflows with production-grade security patterns. NOT for: frontend UI, DevOps deployment, performance optimization, testing strategy.
Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security, covering Web application vulnerabilities, Security review and Secure coding. The repository describes itself as: Agentic development harness for Claude Code — SPEC-driven plan/run/sync, TRUST 5 quality gates, model+effort routing, and Claude×GLM multi-LLM cost control. Single Go binary, 16… The licence is Apache-2.0.
Read from SKILL.md and the folder at commit 2aab5f7. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Moai Ref Owasp Checklist loads about 2.3k tokens when it runs. Until then it costs about 88 tokens; SKILL.md has 904 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

|---|---|---|---|
| A1 | BOLA (Broken Object Level Authorization) | Can user A access user B's resources? | Verify object ownership at every endpoint |
| A2 | Broken Authentication | Weak passwords, unlimited login attempts? | bcrypt (cost 12+), rate limit, MFA |
| A3 | Broken Object Property Level Authorization | Are hidden fields exposed in responses? | Response DTOs, field-level filtering |
| A4 | Unrestricted Resource Consumption | Can mass requests crash the server? | Rate limiting, enforce pagination limits |
| A5 | Broken Function Level Authorization | Can regular users call admin APIs? | RBAC middleware, permission checks |
| A6 | Unrestricted Access to Sensitive Business Flows | Can a sensitive flow be automated or abused in bulk? | Flow-level rate limits, anomaly detection, challenge on abuse signals |
| A7 | SSRF (Server-Side Request Forgery) | Can URL input reach internal or metadata endpoints? | Egress allowlist, block internal/metadata ranges, validate fetch targets |
| A8 | Security Misconfiguration | Debug mode, verbose errors, or default accounts exposed? | Production-hardened config, security headers, inspect deployed config |
| A9 | Improper Inventory Management | Undocumented, shadow, or old-version endpoints reachable? | Maintain an API inventory; deprecate and decommission old versions |
| A10 | Unsafe Consumption of APIs | Are external/third-party API responses trusted blindly? | Validate external responses against a schema, set timeouts, treat upstream data as untrusted |
| Setting | Recommended Value |
|---|---|
| Access Token Expiry | 15-30 minutes |
| Refresh Token Expiry | 7-14 days |
| Algorithm | RS256 (asymmetric) or HS256 |
| Storage | httpOnly + secure + sameSite cookie |
| Payload | Minimal: userId, role only (no PII) |
| Renewal | Silent refresh or token rotation |
| Header | Value | Purpose |
|---|---|---|
Strict-Transport-Security | max-age=31536000; includeSubDomains | Force HTTPS |
X-Content-Type-Options | nosniff | Prevent MIME sniffing |
X-Frame-Options | DENY or SAMEORIGIN | Prevent clickjacking |
Content-Security-Policy | default-src 'self' | Prevent XSS |
Referrer-Policy | strict-origin-when-cross-origin | Limit referrer |
Permissions-Policy | camera=(), microphone=() | Restrict browser features |
| Type | Method | Tool |
|---|---|---|
| Schema validation | Type + structure check | Zod, Joi, pydantic, Go validator |
| Length limits | Min/max constraints | Schema definitions |
| SQL Injection | Parameterized queries | ORM (Prisma, GORM, SQLAlchemy) |
| XSS Prevention | HTML escaping | DOMPurify (client), server escape |
| Path Traversal | Path normalization | filepath.Clean + whitelist |
| File Upload | Type + size validation | MIME type + magic number check |
| CORS | Origin whitelist | Never origin: '*' with credentials |
| Data Type | Storage | Transmission | Logging |
|---|---|---|---|
| Passwords | bcrypt hash only | HTTPS only | NEVER |
| API Keys | Environment variables | Header (Authorization) | Masked (first 4 chars) |
| PII | Encrypted (AES-256) | HTTPS only | Masked |
| Credit Cards | Tokenized (payment provider) | Provider SDK | NEVER |
| Sessions | httpOnly cookie | HTTPS only | NEVER |
| Level | Label | Action | Example |
|---|---|---|---|
| P0 | CRITICAL | Block release | SQL injection, auth bypass |
| P1 | HIGH | Fix before merge | Missing authorization check |
| P2 | MEDIUM | Fix within sprint | Weak password policy |
| P3 | LOW | Track in backlog | Missing security header |
| Principle | Applies To | Defense |
|---|---|---|
| Cached/client-supplied session state is not proof of current identity | Any framework caching or locally decoding a session/JWT value | Re-verify identity against the server-side source of truth (session store, token introspection, identity provider) before every authorization decision |
| Edge/gateway/middleware auth checks are a UX convenience, not a security boundary | Reverse proxies, framework middleware, API gateways, serverless edge functions | Every mutation-handling endpoint independently re-checks authentication AND resource-ownership authorization |
| Scheduled/cron-triggered HTTP endpoints are still public URLs | Any scheduler that invokes an HTTP endpoint (cron jobs, scheduled serverless functions, container-orchestrator scheduled jobs) | Require a shared-secret bearer check (constant-time compare) on every scheduled-endpoint invocation |
| Production builds must not expose source maps or equivalent debug artifacts | Any bundler/build tool | Disable production source maps, verbose stack traces, and build manifests in production configuration |
| Webhook receivers must verify a signature/HMAC header before trusting the payload | Any webhook provider | Verify signature/HMAC against a shared secret before treating the payload as legitimate business data |
<!-- moai:evolvable-start id="rationalizations" -->
| Rationalization | Reality |
|---|---|
| "This is an internal application, OWASP does not apply" | Internal applications are reachable from compromised internal services. OWASP applies to all web applications. |
| "The framework handles XSS protection" | Frameworks protect default rendering paths. Dynamic HTML insertion, innerHTML, and template literals bypass the protection. |
| "We do not store sensitive data, so encryption is unnecessary" | Session tokens, API keys, and PII are sensitive data. If the application has users, it has sensitive data. |
| "Security headers are just defense-in-depth, not critical" | Each security header blocks a specific attack class. Missing CSP enables XSS even when output is escaped. |
| "I will do a security review before release" | Late security reviews find issues that are expensive to fix. Secure coding practices prevent them from the start. |
