CVE-2026-44617: CWE-90 Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection') in Apache Software Foundation Apache Zeppelin
Apache Zeppelin versions 0.11.1, 0.11.2, and 0.12.0 contain an LDAP injection vulnerability due to improper escaping of special characters in LDAP search filters. This vulnerability is an incomplete fix of a previous issue (CVE-2024-31867). The issue is resolved in version 0.12.1. The CVSS score is 6.5, indicating a medium severity risk.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-44617) in Apache Zeppelin arises because the LdapRealm component uses RFC 4514 distinguished-name escaping instead of RFC 4515 filter escaping when constructing LDAP search filters. This results in insufficient escaping of special filter characters, leading to LDAP injection risks. The flaw affects versions 0.11.1, 0.11.2, and 0.12.0 and is a partial regression of CVE-2024-31867. The vendor has addressed the issue in version 0.12.1.
Potential Impact
An attacker could exploit this vulnerability to manipulate LDAP queries by injecting special characters that are not properly escaped. This could lead to unauthorized information disclosure or modification of LDAP query results. The CVSS score of 6.5 reflects a medium impact on confidentiality and integrity, with no impact on availability.
Mitigation Recommendations
Users should upgrade Apache Zeppelin to version 0.12.1, which contains the official fix for this LDAP injection vulnerability. No other mitigation steps are indicated by the vendor. Patch status is confirmed by the vendor advisory stating the fix is in version 0.12.1.
