To address issues related to Cross-Site Request Forgery (CSRF) in Salesforce B2C Commerce, adding CSRF protection middleware in the controller is a recommended approach. This middleware manages the validation of CSRF tokens automatically and ensures that requests are genuine and originating from authenticated users.
By incorporating csrfProtection middleware, any form submissions or state-changing operations are checked for a valid CSRF token, thereby preventing unauthorized actions. This practice is critical for securing web applications against CSRF attacks, where unauthorized commands are transmitted from a user that the web application trusts. Implementing this middleware effectively mitigates such vulnerabilities by ensuring that every sensitive request is accompanied by a valid, unique CSRF token.
