    Spring Security - Cross-Site Request Forgery 🔒

    CSRF (Cross-Site Request Forgery) is an attack where a malicious actor tricks an authenticated user into performing unwanted actions on a web application. This happens as browsers automatically include user credentials with web requests. The post provides a detailed explanation using diagrams, explaining how such an attack works and emphasizing the importance of implementing defenses like anti-CSRF tokens and SameSite cookies to mitigate risks. It also mentions that Spring Security handles CSRF attack prevention by default.
