{"id":"CVE-2026-44616","summary":"Apache Zeppelin: LDAP injection in ActiveDirectoryGroupRealm filter construction","details":"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.","modified":"2026-08-12T03:51:27.190275411Z","published":"2026-07-30T15:21:21.609Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44616.json","cna_assigner":"apache","cwe_ids":["CWE-90"]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/07/30/3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44616.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/p6llqpvcszpg1wc8kx5ncfkdbms3g0rn"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44616"},{"type":"FIX","url":"https://github.com/apache/zeppelin/pull/5226"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/zeppelin","events":[{"introduced":"fa2c0ff93cca49428df8792e7ee35d2b561669bd"},{"fixed":"ae9cb72ffaa6b3c007f57b152e2a3eb2208b910a"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:apache:zeppelin:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0.6.0"},{"fixed":"0.12.1"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44616.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N"}]}
