CSRF (Cross-Site Request Forgery) is a type of attack that manipulates a user's browser to send unauthorized requests to a site where they are authenticated, like an online banking portal.
Spring Security provides protection against CSRF by generating tokens for each session and request, but this may not be suitable for REST APIs where users interact differently.
You should disable CSRF in Spring Security if working with REST APIs, as the traditional CSRF protection may not be effective in such scenarios.
You should not disable CSRF in Spring Security if dealing with traditional websites where users mostly interact via forms, as CSRF protection is crucial in preventing unauthorized actions.
