APIs have become the primary attack surface for many digital businesses. Authorization flaws are often more dangerous than classic injection bugs because a valid token can let an attacker reach other users’ objects.
Minimum controls include proper OAuth/OIDC, object-level authorization (BOLA/IDOR), rate limiting, transactional logging, and WAF/API gateway protections. Each control needs a technical owner and acceptance tests.
Keep tokens short-lived, harden refresh flows, and limit scopes to the minimum required. Admin and internal endpoints should not be reachable from the public internet without extra controls.
Do not rate-limit only login; sensitive operations such as transfers, profile changes, and token issuance also need ceilings and abuse detection. Wire unusual traffic patterns into the SOC.
Keep OpenAPI docs current and make security tests part of the pipeline. Many leaks come from forgotten endpoints or old API versions still open on the gateway.
In Hoxy reports, API findings are usually explained with a business-abuse scenario so product teams see real severity—not only a vulnerability code.
