Most API breaches don’t come from advanced hacking techniques—they come from repeated, basic design failures. Across recent real-world incidents, five issues dominate: broken object-level authorization (BOLA), weak authentication, excessive data exposure, misconfiguration/SSRF, and poor API inventory management. These problems persist because APIs are built to trust requests by default. Until that changes, the same security failures will continue causing large-scale breaches across industries.
