The Current State of Web Application Security Flaws in Late 2025 As I write this on May 11, 2026, the web application threat landscape continues its relentless evolution. The foundational principles of application security remain, but the attack surface, enabled by microservices, serverless architectures, and ubiquitous API integrations, has fragmented dramatically. We're seeing a shift from monolithic application exploitation to lateral movement within distributed systems, often initiated through a seemingly minor web application flaw. The OWASP Top 10, while still a critical baseline, needs to be interpreted through the lens of these modern architectures. Injection flaws (A01:2021) are still prevalent, but their impact can now be amplified across numerous interconnected services. Broken Access Control (A04:2021) isn't just about unauthorized user access; it’s about service-to-service a
