Access Control Failures: The Gateway to Complete Server Compromise

With 94% of applications vulnerable to broken access control according to OWASP, this vulnerability class poses the greatest security risk in production systems today. Real-world exploits are remarkably simple—attackers can enumerate sequential IDs or inject privilege fields into requests—yet most developers focus exclusively on authentication while neglecting authorization checks across every endpoint. The consequences are severe: complete data exfiltration, privilege escalation to admin, and full server compromise.
