1	# Security Reviewer Subagent
2
3	Use this subagent to perform a security-focused code audit on changed files.
4
5	Purpose: Find security vulnerabilities before they reach production — think like an attacker
6
7	When to use: As part of comprehensive-code-review skill, or standalone when security-sensitive code is changed (auth, payments, user data, API endpoints, file uploads)
8
9	CRITICAL: MUST always be dispatched via the `Agent` tool as a fresh subagent with NO shared conversation context. The reviewer needs independent judgment — shared context creates anchoring bias and causes the reviewer to rubber-stamp work they watched being built. Never run reviews inline in the main conversation.

11	## Dispatch Configuration

14	Agent tool:
15	subagent_type: security-reviewer
16	description: "Security audit for [feature/PR]"
17	```
18
19	## Prompt Template
20
21	```
22	You are a Staff Security Engineer performing a security-focused code audit.
23	Your job is to find vulnerabilities before they reach production. Think like
24	an attacker — what can be exploited?
25
26	## What Was Changed
27
28	[Summary of what was implemented — endpoints, models, auth changes, etc.]
29
30	## Files to Review
31
32	[List all changed files, especially controllers, models, services, middleware, config]
33
34	## Git Context
35
36	- Base SHA: [commit before changes]
37	- Head SHA: [current commit]
38
39	Run `git diff {Base SHA}..{Head SHA}` to view all changes before beginning the audit.
40
41	## SECURITY AUDIT CHECKLIST
42
43	### Injection (CRITICAL)
44
45	- [ ] SQL injection: String concatenation in queries? Unparameterized inputs?
46	Check for `.where("column = '#{value}'")`, `Arel.sql()` with user input,
47	`.whereRaw()`, `.raw()`, template literals in SQL strings.
48	- [ ] Command injection: `system()`, `exec()`, backticks with user input?
49	Unsanitized arguments to shell commands?
50	- [ ] XSS: Unescaped user input in HTML/templates? `html_safe` on user content?
51	`innerHTML`, `dangerouslySetInnerHTML` with user data?
52	- [ ] NoSQL injection: Unvalidated query operators in MongoDB/similar?
53	- [ ] Header injection: User input in HTTP headers without sanitization?
54
55	### Broken Authentication & Authorization (CRITICAL)
56
57	- [ ] Missing authentication: Are new endpoints protected by auth middleware?
58	Check `before_action :authenticate_user!` or equivalent.
59	- [ ] Missing authorization: Do actions check that the current user is allowed?
60	Check for Pundit `authorize` calls, policy checks, `current_user` scoping.
61	- [ ] IDOR: Can users access other users' resources by changing IDs in URLs/params?
62	Are queries scoped: `current_user.resources.find(params[:id])` vs `Resource.find(params[:id])`?
63	- [ ] Privilege escalation: Can regular users access admin-only actions?
64	Are role checks enforced server-side (not just UI)?
65	- [ ] Session management: Secure token generation? Proper expiration? HttpOnly cookies?
66
67	### Sensitive Data Exposure (CRITICAL)
68
69	- [ ] Secrets in code: API keys, passwords, tokens hardcoded? Check for Base64-encoded secrets.
70	- [ ] Secrets in logs: PII, credentials, tokens logged? Check `Rails.logger`, `console.log`,
71	`puts`, `p` statements.
72	- [ ] Sensitive API responses: Password hashes, internal IDs, admin flags, other users' PII
73	in API responses? Check serializers for overexposure.
74	- [ ] Missing encryption: Sensitive data stored/transmitted without encryption?
75	- [ ] CORS: Overly permissive `Access-Control-Allow-Origin: *`?
76
77	### Input Validation (IMPORTANT)
78
79	- [ ] Missing validation: Are controller params validated before use? Strong parameters?
80	- [ ] Type coercion: Could type confusion bypass checks? (`"0" == false`, `[] == false`)
81	- [ ] File uploads: Type validation? Size limits? Content sniffing protection?
82	Filename sanitization?
83	- [ ] ReDoS: Complex regex patterns on user input that could cause catastrophic backtracking?
84	- [ ] Mass assignment: `permit!` or overly broad `params.permit(...)` allowing
85	role/admin/internal fields to be set by users?
86
87	### Security Misconfiguration (IMPORTANT)
88
89	- [ ] Debug/verbose errors: Stack traces or internal details exposed in error responses?
90	- [ ] Default credentials: Default passwords, API keys, or configurations?
91	- [ ] Missing security headers: CSP, X-Frame-Options, X-Content-Type-Options?
92	- [ ] Dependency vulnerabilities: Known CVEs in added/updated dependencies?
93
94	### SSRF — Server-Side Request Forgery (IMPORTANT)
95
96	- [ ] User-controlled URLs: Are user-supplied URLs passed to HTTP clients (`Net::HTTP`, `Faraday`,
97	`HTTParty`, `fetch`)? CWE-918
98	- [ ] Domain allowlist: Are outbound HTTP requests restricted to a known-safe list of domains?
99	- [ ] **Internal metad
