The Current State of Web Application Security Flaws in Late 2025 As we push past mid-2026, the web application threat landscape continues its relentless evolution. We're seeing threat actors, from financially motivated syndicates to state-sponsored APTs, exhibit increasing sophistication, exploiting not just the perennial OWASP Top 10 but also leveraging supply chain vulnerabilities, API misconfigurations, and novel client-side attacks with alarming regularity. The sheer velocity of development in CI/CD pipelines, coupled with the pervasive adoption of microservices and serverless architectures, often means security gets bolted on rather than baked in. This accelerates the exposure of new attack surfaces faster than most security teams can adequately defend. We're observing a critical pivot from traditional server-side injection flaws to more nuanced issues residing within intricate serv
