Documentation

xssProtection will prevent the browser from rendering content when a Cross-Site Scripting attack is being detected. However, this will not work for browsers which do not use the X-XSS protection header. Adding a Content-Security-Policy header will provide additional protection against XSS attacks and data injections.

Before
http.headers().xssProtection();
After
http.headers().xssProtection().and().contentSecurityPolicy("script-src 'self'");
