As APIs become the backbone of digital services, their security is more critical than ever. In recent years, API-related attacks have surged dramatically. Reports reveal that 57% of organizations have suffered from exposed APIs, and API incidents increased to 37% in 2024, up from 17% in 2023. Alarmingly, 61% of attackers gained access without authentication, highlighting the urgent need for stronger defenses.
APIs are increasingly targeted because they expose valuable data and business functions. With generative AI expanding attack surfaces, API abuse is expected to become the most common attack vector by 2025. Businesses must take proactive steps to secure their APIs.

Top API Security Risks

1. Broken Object Level Authorization (BOLA) – Attackers modify object IDs to access unauthorized data.
   Fix: Enforce access control checks and use indirect references like UUIDs.
   
2. Broken Authentication – Weak tokens, poor storage practices, and no MFA lead to compromise.
   Fix: Use OAuth 2.0, enable MFA, and rotate API keys regularly.
   
3. Broken Object Property Level Authorization – APIs allow modification of sensitive fields like roles.
   Fix: Whitelist input fields and validate schemas.
   
4. Unrestricted Resource Consumption – Lack of rate limiting leads to DoS and DDoS attacks.
   Fix: Implement rate limits and AI-based traffic monitoring.
   
5. Broken Function Level Authorization – Attackers use admin functions through unprotected endpoints.
   Fix: Apply role-based access controls and centralized policy enforcement.
   
6. Unrestricted Access to Business Flows – Bots exploit APIs to automate high-value transactions.
   Fix: Use CAPTCHAs, biometrics, and monitor abnormal usage patterns.
   
7. Server-Side Request Forgery (SSRF) – APIs fetch malicious URLs, exposing internal systems.
   Fix: Use allowlists, input validation, and sandbox external requests.
   
8. Security Misconfiguration – Weak settings, exposed methods, and verbose errors increase risk.
   Fix: Harden configurations, restrict HTTP methods, and run security audits.
   
9. Improper Inventory Management – Shadow and deprecated APIs become attack points.
   Fix: Maintain an updated API inventory and use discovery tools.
   
10. Unsafe Third-Party API Usage – External APIs may be insecure or deprecated.
    Fix: Validate all inputs/outputs and use SCA tools to check dependencies.
    
11. Injection Attacks – Malicious inputs trigger unintended commands.
    Fix: Use ORMs, input validation, and scanning tools like DAST/SAST.
    
12. Insecure Direct Object References (IDOR) – Direct ID access allows data leaks.
    Fix: Enforce ownership checks and use session-bound IDs.
    
13. Misconfigured CORS Policies – Over-permissive cross-origin requests lead to XSS or CSRF.
    Fix: Use whitelists and limit HTTP methods allowed via CORS.
    
14. Insufficient Logging & Monitoring – Attacks go unnoticed without visibility.
    Fix: Centralize logs, set alerts, and monitor unusual activity.
