AGMP Partners It's September 12, 2026, and as I reflect on the web application security landscape, it's clear that while the foundational principles remain, the attack surface has mutated. We've moved beyond simple SQLi and XSS being the primary concerns, though these still plague poorly managed applications. Today, the real battles are fought at the intersection of complex microservices architectures, serverless functions, API gateways, and the pervasive use of third-party components. The OWASP Top 10, while an indispensable baseline, often feels like a snapshot from a simpler time. Attackers are more sophisticated, their methods often chaining multiple, seemingly minor vulnerabilities to achieve significant impact. The Current State of Web Application Security Flaws in Late 2025 The threat landscape by late 2025 has become significantly more dynamic. The rapid adoption of cloud-native
