What is a CSRF attack?

CSRF tricks your authenticated browser into unwanted actions on another site, like fake transfers or deletes — no password needed.

How do I prevent CSRF in my web app?

Use anti-CSRF tokens in forms/headers, SameSite cookies, and safe GETs for reads only. Check frameworks like Express.js csurf middleware.

Does CSRF affect SPAs like React or Vue?

Yes — AJAX/fetch requests need custom headers or tokens; SameSite helps but verify mutating endpoints.
