The Current State of Web Application Security Flaws in Late 2025 As we navigate late 2025, the web application threat landscape has matured significantly, but not necessarily for the better. We're seeing a relentless evolution of attack methodologies, often leveraging the very same technological innovations meant to accelerate development and deployment. The shift towards microservices, APIs, and serverless architectures, while offering agility, has simultaneously exploded the attack surface. Traditional perimeter defenses are increasingly irrelevant when dealing with distributed systems housing hundreds, if not thousands, of interconnected APIs, many exposed to the internet. We're observing a disturbing trend where basic vulnerabilities, often present in the OWASP Top 10 for years, are still prevalent, merely manifesting in new contexts. For instance, Injection flaws (A03:2021) aren't j
