CVE-2026-44616: CWE-90 Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection') in Apache Software Foundation Apache Zeppelin
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.
AI Analysis
Technical Summary
CVE-2026-44616 is an LDAP injection vulnerability in Apache Zeppelin affecting versions 0.6.0 through 0.12.0. The ActiveDirectoryGroupRealm component fails to properly escape user input in LDAP search filters, enabling an authenticated attacker to inject LDAP filter syntax through the user-search endpoint and the role-lookup path. This can lead to unauthorized exposure of directory information. The issue is fixed in Apache Zeppelin version 0.12.1.
Potential Impact
An authenticated attacker can exploit this vulnerability to inject LDAP filter syntax, potentially exposing sensitive directory information. This could lead to unauthorized disclosure of user or group data stored in the LDAP directory. There is no indication of remote unauthenticated exploitation or privilege escalation beyond the authenticated context.
Mitigation Recommendations
Users should upgrade Apache Zeppelin to version 0.12.1, which fixes the LDAP injection vulnerability by properly escaping user-controlled input in LDAP queries. No other mitigation or temporary workaround is indicated in the provided data.
