API Security Review
Perform comprehensive API security assessment following plays/api-security-review.md.
Steps
- Discovery & Reconnaissance
- Parse OpenAPI/Swagger specs or scan code for endpoints
- Identify authentication mechanisms (JWT, OAuth 2.0, API keys, mTLS)
- Map API gateway and middleware configurations
- Enumerate all API versions and deprecated endpoints
- Authentication Deep Dive
- JWT security (algorithm confusion, weak signing, token expiration)
- OAuth 2.0 flows (PKCE, state parameter, redirect URI validation)
- API key exposure and rotation policies
- Session management and token storage
- Assess All 10 OWASP API Risks with attack scenarios:
- API1 BOLA — IDOR via predictable IDs, batch endpoint bypasses, ownership verification gaps
- API2 Broken Authentication — JWT attacks, OAuth flaws, brute force, credential stuffing
- API3 BOPA — Mass assignment, response over-exposure, field-level authz bypasses
- API4 Resource Consumption — Rate limit bypasses, pagination abuse, GraphQL DoS
- API5 BFLA — Admin endpoint discovery, horizontal/vertical privilege escalation
- API6 Business Flows — Automated abuse, inventory exhaustion, scraping attacks
- API7 SSRF — URL bypasses, DNS rebinding, cloud metadata access
- API8 Misconfiguration — CORS bypasses, verbose errors, missing headers
- API9 Inventory — Shadow APIs, zombie endpoints, version confusion
- API10 Unsafe Consumption — XXE, deserialization, webhook replay attacks
- Automated Testing
- Run API security scanners (OWASP ZAP, Burp Suite, Postman tests)
- Test for common vulnerabilities with specific payloads
- Validate rate limiting and throttling mechanisms
- API Gateway & Infrastructure Review
- Kong, nginx, Envoy, AWS API Gateway configurations
- WAF rules and bypass opportunities
- TLS configuration and certificate validation
Output
Comprehensive API security report including:
- API surface inventory with authentication mechanisms
- Risk matrix with severity ratings for all 10 categories
- Detailed findings with proof-of-concept examples
- Exploit scenarios and business impact analysis
- Prioritized remediation roadmap with code examples
- Testing artifacts and vulnerability evidence
