What are the main API security risks in 2026?

All answers to this question.

One of the absolute biggest mistakes developers make is relying solely on basic API keys for public endpoint protection, mistakenly believing they act as a robust authorization mechanism rather than a simple identification tag. Another massive oversight is failing to enforce strict Object-Level Authorization (BOLA), where an application authenticates a user but fails to verify if that specific user actually owns the resource ID being requested in the URL parameter. Furthermore, teams routinely return raw database objects in responses, counting on the front-end client interface to filter out sensitive data fields, which exposes internal metadata to anyone inspecting raw network payloads.

Do you think these common authorization lapses are primarily due to developers relying too heavily on automated vulnerability scanners during the CI/CD pipeline, given that standard pattern-matching tools completely miss complex business logic flaws and multi-step authorization manipulation?

• You hit the nail on the head, Arthur. Standard automated scanners are fantastic at catching outdated dependencies or unencrypted traffic flags, but they are fundamentally blind to business logic context. A scanner sees a 200 OK response with data and flags it as a success; it has no way of knowing that User A shouldn't be allowed to view User B's financial records. Fixing this requires mandatory, negative security testing cases written explicitly into your test suites to actively try and access unauthorized IDs.

The biggest trap is treating internal microservices as safe zones, omitting encryption or strict access tokens between containers because they live behind the primary corporate firewall.

• Completely agree with Heather on this one. Relying entirely on perimeter security is a massive liability. If an attacker breaches just one public-facing service, they gain unfettered access to the entire backend cluster. Implementing a strict zero-trust posture with mutual TLS and signed tokens for all internal service-to-service calls is non-negotiable.
