StrictHttpFirewall in spring security 4.2 vs spring MVC @MatrixVariable

You can dilute the default spring security firewall using your custom defined instance of StrictHttpFirewall (at your own risk) @Bean public HttpFirewall allowUrlEncodedSlashHttpFirewall() { StrictHttpFirewall firewall = new StrictHttpFirewall(); firewall.setAllowUrlEncodedSlash(true); firewall.setAllowSemicolon(true); return firewall; } And then use this custom firewall bean in WebSecurity (Spring boot does not need this change) @Override public void configure(WebSecurity web) … Read more
