API Security Vulnerabilities in Production Environments: A Large-Scale Empirical Study

What Did This Cybersecurity Research Find?

This cybersecurity research analyzed API traffic and vulnerability scan results across 500 production environments to categorize the most common API security issues. Cybersecurity teams protecting APIs found that broken object-level authorization (BOLA) and excessive data exposure accounted for 58% of all API vulnerabilities, aligning with OWASP API Security Top 10 priorities.

Key Findings

• 1Broken object-level authorization (BOLA) was the most common API vulnerability at 32%
• 2Excessive data exposure affected 26% of analyzed API endpoints
• 3API authentication bypass vulnerabilities were present in 18% of environments
• 4Organizations with API gateways enforcing schema validation had 47% fewer vulnerabilities
• 5Automated API security testing caught 72% of OWASP API Top 10 issues before production deployment

How Does This Apply to Cybersecurity Careers?

Application security engineers and API developers can focus testing efforts on the most common vulnerability patterns. Entry-level AppSec candidates should prioritize API security knowledge.
