Spring Security recommends the use of StrictHttpFirewall as it rejects malicious URLs instead of trying to sanitize them.
Before:
public void httpFirewall() {
    DefaultHttpFirewall firewall = new DefaultHttpFirewall();
}
After:
public void httpFirewall() {
    StrictHttpFirewall firewall = new StrictHttpFirewall();
}
