A vulnerability has been identified in centraldogma-server-auth-shiro versions prior to 0.84.0, where the SearchFirstActiveDirectoryRealm substitutes the login username into an LDAP search filter without neutralizing LDAP filter metacharacters, allowing an unauthenticated attacker to manipulate the filter to cause authentication confusion and enumerate the directory structure.

## What to do
