CSRF
CSRF (Cross-Site Request Forgery) is a web security vulnerability that allows an attacker to trick a user's browser into making unauthorized requests to a trusted website where the user is authenticated. It exploits the trust that a web application has in a user's browser, typically by embedding malicious requests in links, forms, or scripts on a third-party site. This can lead to actions like changing account settings, making transactions, or deleting data without the user's consent.
Developers should learn about CSRF to build secure web applications that protect against unauthorized actions by authenticated users. It is crucial for any application handling sensitive operations, such as banking, e-commerce, or social media platforms, where user sessions are involved. Understanding CSRF helps implement defenses like anti-CSRF tokens, same-site cookies, and proper request validation to prevent exploitation.
