NewCVE-2026-44616 (opens in a new tab)How to fix?
Upgrade org.apache.zeppelin:zeppelin-server to version 0.12.1 or higher.
Overview
org.apache.zeppelin:zeppelin-server is a web-based notebook that enables interactive data analytics. You can make beautiful data-driven, interactive and collaborative documents with SQL, Scala and more.
Affected versions of this package are vulnerable to LDAP Injection through the searchForUserName and getRoleNamesForUser paths in ActiveDirectoryGroupRealm. An authenticated attacker can inject LDAP filter syntax by supplying crafted usernames or role-lookup input to the user-search endpoint or post-authentication role lookup, causing Zeppelin to build attacker-controlled search filters. This can be used to alter the LDAP query and expose directory information beyond the intended user record. In affected deployments, a malicious authenticated user can enumerate or retrieve unintended LDAP entries during login and group resolution.
