Cross-Site Request Forgery (CSRF)
CSRF is a security vulnerability where attackers trick a user's browser into performing unwanted actions.
Spring Boot provides built-in CSRF protection to prevent such attacks by generating and validating unique tokens.
CSRF represents a particular attack vector that Spring Security guards against, by default.
(Spring Security guards against many attack methods, but most don’t require a policy decision).
It’s a bit technical, but CSRF involves tricking already-authenticated users into clicking on rogue links.
The rogue link asks the user to authorize a request, essentially granting the malicious attacker inside access.
The best way to guard against this is to embed a nonce into secured assets and refuse requests that lack them.
A nonce is a semi-random number generated on the server that marks proper resources.
The nonce is embedded as a CSRF token and must be embedded in any state-changing bits of HTML, typically forms.
To enable CSRF protection in a Spring Boot application, you can follow these steps:
1. By default, Spring Security automatically enables CSRF protection.
So, if you have the Spring Security dependency in your project, CSRF protection is already enabled.
2. By default, Spring Security protects all HTTP methods with CSRF, except GET, HEAD, OPTIONS, and TRACE.
You can customize this behavior if needed.
For example, if you want to disable CSRF protection for a specific endpoint, you can use the csrf().ignoringAntMatchers("/your-endpoint") configuration in your Spring Security configuration class:
In this example, the CSRF protection is disabled for the /your-endpoint URL pattern.
