API Injection Scanner
Tests for various injection vulnerabilities in API parameters.
What is API Injection?
API Injection testing identifies vulnerabilities where API input is passed unsafely to interpreters—SQL databases, NoSQL stores, command shells, LDAP, or expression evaluators. APIs often have larger attack surfaces than web forms because they accept complex nested structures, JSON, and XML.
Why is This Important?
Injection through APIs can be more severe than traditional web injection because APIs handle structured data that may bypass web-focused defenses. Nested JSON, array parameters, and direct database interaction patterns create injection opportunities that standard web scanners miss.
How It Works
1. API Discovery
Automatically discovers API endpoints, methods, parameters, and authentication mechanisms from documentation or traffic.
2. Security Testing
Tests for OWASP API Top 10 vulnerabilities including broken authentication, excessive data exposure, and injection flaws.
3. Compliance Validation
Validates API security against industry standards with detailed findings and remediation guidance.

Frequently Asked Questions
What injection types affect APIs?
API-relevant injections: SQL injection in query parameters, NoSQL injection in JSON bodies, command injection in file processing, LDAP injection in directory queries, XPath/XML injection, expression language injection, and GraphQL injection in resolvers.
How do APIs create unique injection risks?
API-specific risks: JSON parsing creating object injection, array parameters enabling mass operations, nested structures bypassing validation, direct database query patterns (vs. ORM in web), and less sanitization on 'internal' API endpoints.
How do I test APIs for injection?
Testing: fuzz all JSON fields with injection payloads, test array/object injection, examine error messages for backend details, test file upload parameters, check XML processing for XXE, and verify parameterization on all database operations.
How do I prevent API injection?
Prevention: use parameterized queries/prepared statements, implement input validation on all parameters, use ORMs with proper escaping, validate JSON schema, sanitize file operations, disable XML external entities, and apply the principle of least privilege to database connections.
