A comprehensive overview of the top web application security vulnerabilities every developer should know, covering OWASP Top 10 risks including SQL injection, XSS, broken authentication, broken access control, security misconfigurations, sensitive data exposure, vulnerable dependencies, CSRF, SSRF, and insecure deserialization. Each vulnerability is explained with real-world breach examples (MOVEit, Log4Shell, Capital One, British Airways), impact analysis, and prevention strategies. The post also highlights how automated tools like SAST, SCA, secrets detection, and IaC scanning can catch these issues early in the development lifecycle.
