Workaround
If upgrading to a non-vulnerable version is not immediately possible, a temporary workaround is to implement CSRF protection measures within the application. This can include using anti-CSRF tokens, validating the origin of requests, and implementing strict access controls. Here is an example of how to implement anti-CSRF tokens in Java:
// Generate and include anti-CSRF token in forms
String csrfToken = generateCSRFToken();
// Verify anti-CSRF token on form submission
if (request.getParameter("csrfToken").equals(csrfToken)) {
// Process the form submission
} else {
// Handle CSRF attack
}
