Spring security CORS Filter

Question

We added Spring Security to our existing project  From this moment on we get a 401 No  Access-Control-Allow-Origin  header is present on the requested resource error from the our server  That s because no Access-Control-Allow-Origin header is attached to the response  To fix this we added our own filter which is in the Filter chain before the logout filter  but the filter does not apply for our requests  Our Error   XMLHttpRequest cannot load http   localhost 8080 getKunden  No  Access-Control-Allow-Origin  header is present on the requested resource  Origin http   localhost 3000 is therefore not allowed access  The response had HTTP status code 401   Our Security configuration   EnableWebSecurity  Configuration  ComponentScan  quot com company praktikant quot   public class

Since Spring Security 4 1  this is the proper way to make Spring Security support CORS  also needed in Spring Boot 1 4 1 5     Configuration public class WebConfig extends WebMvcConfigurerAdapter         Override     public void addCorsMappings CorsRegistry registry            registry addMapping                         allowedMethods  HEAD    GET    PUT    POST    DELETE    PATCH              and    Configuration public class SecurityConfig extends WebSecurityConfigurerAdapter        Override     protected void configure HttpSecurity http  throws Exception             http csrf   disable            http cors                Bean     public CorsConfigurationSource corsConfigurationSource             final CorsConfiguration configuration   new CorsConfiguration            configuration setAllowedOrigins ImmutableList of                configuration setAllowedMethods ImmutableList of  HEAD                    GET    POST    PUT    DELETE    PATCH                setAllowCredentials true  is important  otherwise             The value of the  Access-Control-Allow-Origin  header in the response must not be the wildcard     when the request s credentials mode is  include           configuration setAllowCredentials true              setAllowedHeaders is important  Without it  OPTIONS preflight request            will fail with 403 Invalid CORS request         configuration setAllowedHeaders ImmutableList of  Authorization    Cache-Control    Content-Type             final UrlBasedCorsConfigurationSource source   new UrlBasedCorsConfigurationSource            source registerCorsConfiguration        configuration           return source            Do not do any of below  which are the wrong way to attempt solving the problem    http authorizeRequests   antMatchers HttpMethod OPTIONS         permitAll    web ignoring   antMatchers HttpMethod OPTIONS     Reference  http   docs spring io spring-security site docs 4 2 x reference html cors html

Ok  after over 2 days of searching we finally fixed the problem  We deleted all our filter and configurations and instead used this 5 lines of code in the application class   SpringBootApplication public class Application       public static void main String   args            final ApplicationContext ctx   SpringApplication run Application class  args               Bean     public WebMvcConfigurer corsConfigurer             return new WebMvcConfigurerAdapter                  Override             public void addCorsMappings CorsRegistry registry                    registry addMapping  quot     quot   allowedOrigins  quot http   localhost 3000 quot

There s 8 hours of my life I will never get back     Make sure that you set both Exposed Headers AND Allowed Headers in your CorsConfiguration   Bean CorsConfigurationSource corsConfigurationSource         CorsConfiguration configuration   new CorsConfiguration        configuration setAllowedOrigins Collections singletonList  http   localhost 3000         configuration setAllowedMethods Arrays asList  GET   POST    PUT    DELETE    PATCH    OPTIONS         configuration setExposedHeaders Arrays asList  Authorization    content-type         configuration setAllowedHeaders Arrays asList  Authorization    content-type         UrlBasedCorsConfigurationSource source   new UrlBasedCorsConfigurationSource        source registerCorsConfiguration        configuration       return source

With Spring Security in Spring Boot 2 to configure CORS globally  e g  enabled all request for development  you can do    Bean protected CorsConfigurationSource corsConfigurationSource         UrlBasedCorsConfigurationSource source   new UrlBasedCorsConfigurationSource        source registerCorsConfiguration        new CorsConfiguration   applyPermitDefaultValues         return source      Override protected void configure HttpSecurity http  throws Exception       http cors                and   authorizeRequests                anyRequest   permitAll                and   csrf   disable

You don t need    Configuration  ComponentScan  com company praktikant      EnableWebSecurity already has   Configuration in it  and I cannot imagine why you put  ComponentScan there  About CORS filter  I would just put this    Bean public FilterRegistrationBean corsFilter         UrlBasedCorsConfigurationSource source   new UrlBasedCorsConfigurationSource        CorsConfiguration config   new CorsConfiguration        config setAllowCredentials true       config addAllowedOrigin           config addAllowedHeader           config addAllowedMethod           source registerCorsConfiguration        config       FilterRegistrationBean bean   new FilterRegistrationBean new CorsFilter source        bean setOrder 0        return bean      Into SecurityConfiguration class and remove configure and configure global methods  You don t need to set allowde orgins  headers and methods twice  Especially if you put different properties in filter and spring security config    According to above  your  MyFilter  class is redundant  You can also remove those   final AnnotationConfigApplicationContext annotationConfigApplicationContext   new AnnotationConfigApplicationContext    annotationConfigApplicationContext register CORSConfig class   annotationConfigApplicationContext refresh      From Application class  At the end small advice - not connected to the question  You don t want to put verbs in URI  Instead of http   localhost 8080 getKunden you should use HTTP GET method on http   localhost 8080 kunden resource  You can learn about best practices for design RESTful api here  http   www vinaysahni com best-practices-for-a-pragmatic-restful-api

In many places  I see the answer that needs to add this code       Bean public FilterRegistrationBean corsFilter        UrlBasedCorsConfigurationSource source   new UrlBasedCorsConfigurationSource       CorsConfiguration config   new CorsConfiguration       config setAllowCredentials true      config addAllowedOrigin          config addAllowedHeader          config addAllowedMethod          source registerCorsConfiguration        config      FilterRegistrationBean bean   new FilterRegistrationBean new CorsFilter source       bean setOrder 0       return bean      but in my case  it throws an unexpected class type exception  corsFilter   bean requires CorsFilter type  so I have done this changes and put this definition of bean in my config and all is OK now    Bean public CorsFilter corsFilter         UrlBasedCorsConfigurationSource source   new UrlBasedCorsConfigurationSource        CorsConfiguration config   new CorsConfiguration        config setAllowCredentials true       config addAllowedOrigin           config addAllowedHeader           config addAllowedMethod           source registerCorsConfiguration        config       return new CorsFilter source

I had a similar problem but with the specific requirement to have the CORS header set from decorators in our endpoints  like this   CrossOrigin origins    quot   quot   allowCredentials    quot true quot    PostMapping value    quot  login quot    Or  CrossOrigin origins    quot   quot    GetMapping value    quot  verificationState quot    So simply intercepting the request  setting the CORS header manually and sending 200 back was not an option  because allowCredentials was needed to be true in some cases and wildcards are not allowed then  Sure  a CORS registry would have helped  but since our clients are angular in capacitor on android and iOS  there is no specific domain to register  So the clean way to do - in my opinion - is to pipe preflights directly to the endpoints to let them handle it  I solved it with this   Component public class PreflightFilter extends OncePerRequestFilter        private static final Logger logger   LoggerFactory getLogger PreflightFilter class         Override     protected void doFilterInternal HttpServletRequest request                                      HttpServletResponse response  FilterChain chain              throws ServletException  IOException            if  CorsUtils isPreFlightRequest request                 logger info  quot Preflight request accepted quot                SecurityContextHolder getContext   setAuthentication createPreflightToken request                      chain doFilter request  response              private UsernamePasswordAuthenticationToken createPreflightToken HttpServletRequest request            UserDetails userDetails   new User  quot Preflight quot    quot  quot                   true  true  true  true                  Stream of new SimpleGrantedAuthority  quot AppUser quot    collect Collectors toSet              UsernamePasswordAuthenticationToken preflightToken                   new UsernamePasswordAuthenticationToken                          userDetails  null  userDetails getAuthorities             preflightToken                  setDetails new WebAuthenticationDetailsSource   buildDetails request            return preflightToken           Keep in mind that the endpoint decorators don t work like wildcards here as one would expect

Since i had problems with the other solutions  especially to get it working in all browsers  for example edge doesn t recognize     as a valid value for  Access-Control-Allow-Methods    i had to use a custom filter component  which in the end worked for me and did exactly what i wanted to achieve    Component  Order Ordered HIGHEST PRECEDENCE  public class CorsFilter implements Filter       public void doFilter ServletRequest req  ServletResponse res  FilterChain chain              throws IOException  ServletException           HttpServletResponse response    HttpServletResponse  res          HttpServletRequest request    HttpServletRequest  req          response setHeader  Access-Control-Allow-Origin                 response setHeader  Access-Control-Allow-Credentials    true            response setHeader  Access-Control-Allow-Methods                    ACL  CANCELUPLOAD  CHECKIN  CHECKOUT  COPY  DELETE  GET  HEAD  LOCK  MKCALENDAR  MKCOL  MOVE  OPTIONS  POST  PROPFIND  PROPPATCH  PUT  REPORT  SEARCH  UNCHECKOUT  UNLOCK  UPDATE  VERSION-CONTROL            response setHeader  Access-Control-Max-Age    3600            response setHeader  Access-Control-Allow-Headers                    Origin  X-Requested-With  Content-Type  Accept  Key  Authorization             if   OPTIONS  equalsIgnoreCase request getMethod                   response setStatus HttpServletResponse SC OK             else               chain doFilter req  res                        public void init FilterConfig filterConfig               not needed            public void destroy               not needed

According the CORS filter documentation    quot Spring MVC provides fine-grained support for CORS configuration through annotations on controllers  However when used with Spring Security it is advisable to rely on the built-in CorsFilter that must be ordered ahead of Spring Security   s chain of filters quot   Something like this will allow GET access to the  ajaxUri   Component  Order Ordered HIGHEST PRECEDENCE  public class AjaxCorsFilter extends CorsFilter       public AjaxCorsFilter             super configurationSource                private static UrlBasedCorsConfigurationSource configurationSource             CorsConfiguration config   new CorsConfiguration                origins         config addAllowedOrigin  quot   quot                when using ajax  withCredentials  true  we require exact origin match         config setAllowCredentials true               headers         config addAllowedHeader  quot x-requested-with quot                methods         config addAllowedMethod HttpMethod OPTIONS           config addAllowedMethod HttpMethod GET            UrlBasedCorsConfigurationSource source   new UrlBasedCorsConfigurationSource            source registerCorsConfiguration  quot  startAsyncAuthorize quot   config           source registerCorsConfiguration  quot  ajaxUri quot   config           return source           Of course  your SpringSecurity configuration must allow access to the URI with the listed methods  See  Hendy Irawan answer
