The Current State of Web Application Security Flaws in Late 2025 As I sit here on June 11, 2026, reflecting on the web application security landscape, it’s clear that while the fundamentals of threat vectors haven't radically shifted, their sophistication and scale have. We’re still battling Cross-Site Scripting (XSS), SQL Injection, and broken authentication, but the attack surface has exploded with the proliferation of API-driven architectures, serverless functions, and complex microservices. The days of monolithic applications behind a single perimeter firewall are largely behind us, replaced by distributed systems where trust boundaries are far more granular and ephemeral. What distinguishes the current threat environment from even a few years ago is the widespread adoption of AI/ML-driven tooling by threat actors, making reconnaissance and payload generation significantly more effic
