The Current State of Web Application Security Flaws in Late 2025 Alright team, let's talk web application security, specifically as we sit here in September 2026. The landscape is shifting, and while the core vulnerabilities identified by OWASP a decade ago still plague us, the attack vectors and sophistication have evolved dramatically. We're seeing fewer trivial SQLi and XSS against well-maintained, modern frameworks, but the low-hanging fruit has simply moved. Attackers are now targeting misconfigurations in cloud-native deployments, supply chain dependencies in complex microservice architectures, and the pervasive API sprawl that defines most enterprise ecosystems. Authentication and Authorization flaws, often manifesting as BOLA (Broken Object Level Authorization) or BFLA (Broken Function Level Authorization), are rampant in RESTful and GraphQL APIs. Moreover, client-side vulnerabil
