Broken Object Level Authorization (BOLA) is still, by a wide margin, the most common critical finding I report on API engagements — and it's rarely subtle once you know where to look.
This post ranks the OWASP API Top 10 categories by real-world frequency based on my own engagement history, with concrete examples of how each one typically manifests in production APIs.
I close with a practical checklist developers can run through before their API ever reaches a pentester — the fixes that would have prevented most of what I find.
