CSRF tokens are random values that are generated by the server and included in requests that perform state-changing actions. They are used to prevent CSRF attacks by verifying that the request originates from a legitimate source. However, if the CSRF tokens are transmitted using cookies, they are vulnerable to being stolen or forged by an attacker who can exploit other vulnerabilities, such as cross-site scripting (XSS) or cookie injection. Therefore, a better option is to avoid the transmission of CSRF tokens using cookies and use other methods, such as hidden form fields or custom HTTP headers.
