LDAP injection vulnerability in Apache Zeppelin. ActiveDirectoryGroupRealm constructed LDAP search filters without escaping user-controlled input, allowing an authenticated attacker to inject LDAP filter syntax through the user-search endpoint                   and potentially expose directory information. The role-lookup path was also affected after successful LDAP authentication. This issue affects Apache Zeppelin versions 0.6.0 through 0.12.0. Users are recommended to upgrade to version 0.12.1, which                   fixes this issue.
