Introduction OWASP released the Top 10:2025 at its Global AppSec conference in November 2025, finalizing it in January 2026, its first update since 2021 [1]. The list is built from analysis of more than 175,000 CVE records across roughly 2.8 million applications, combined with a practitioner survey, and the changes it introduces are not cosmetic [2]. Two categories are new. One long-standing category jumped three places. And the underlying data suggests that the way most organizations test their APIs and applications has not kept pace with where the risk actually sits. For AppSec engineers and platform teams directly responsible for API testing programs, this update is wo…

Frequently Asked Questions

What's the single biggest change in OWASP Top 10:2025 for API teams?

Security Misconfiguration's jump from fifth to second place, combined with the new Software Supply Chain Failures category at third, both signal that continuous, behavioral testing now matters more than periodic, CVE-lookup-based scanning [1][2].
Does the general OWASP Top 10:2025 replace the API-specific Top 10?

No. The API-specific list, last updated in 2023, remains the more detailed reference for authentication and authorization failure patterns. The 2025 general update confirms the same failure patterns hold across application security broadly [1][6].
