API Security Scanner

APIs now handle 83% of all internet traffic. They're also the most frequently attacked component of modern applications, with API-specific vulnerabilities growing 400% since 2020.

Common API Vulnerabilities

• Broken Object Level Authorization (BOLA) — Accessing other users' data by changing IDs
• Broken Authentication — Weak tokens, missing rate limits, improper session handling
• Excessive Data Exposure — APIs returning more data than the frontend needs
• Mass Assignment — Attackers modifying fields they shouldn't have access to
• Injection — SQL, NoSQL, and command injection through API parameters
• Rate Limiting — Missing or weak throttling enabling brute force attacks

How do I test API security?

Enter your API's base URL in VulnScan. We analyze endpoint responses, authentication mechanisms, error handling, and common vulnerability patterns.

What is BOLA?

Broken Object Level Authorization — the #1 API vulnerability. It occurs when an API doesn't verify that the requesting user should have access to the specific object they're requesting. Attackers change ID values to access other users' data.

Are GraphQL APIs more vulnerable?

GraphQL APIs face unique risks including introspection exposure, query depth attacks, and batch query abuse. They require specific security controls beyond traditional REST API protections.
