AGMP Partners The Current State of Web Application Security Flaws in Late 2025 As we navigate late 2025, approaching the midpoint of 2026, the landscape of web application security flaws has evolved considerably. While the OWASP Top 10 remains a foundational benchmark for identifying critical risks, relying solely on it for a comprehensive security posture is now insufficient. The threat actors have become far more sophisticated, moving beyond traditional injection and broken authentication attacks to encompass more subtle and systemic vulnerabilities. We're seeing a significant uptick in supply chain attacks targeting application dependencies, the exploitation of misconfigured cloud-native services housing critical application components, and advanced client-side attacks that bypass traditional server-side protections. The widespread adoption of microservices architectures, serverless f
