CVE detail

CVE-2026-44617

LDAP filter injection vulnerability in Apache Zeppelin. LdapRealm used RFC 4514 distinguished-name escaping when constructing LDAP search filters instead of RFC 4515 filter escaping, leaving special filter characters insufficiently escaped. This is an incomplete fix of CVE-2024-31867. This issue affects Apache Zeppelin versions 0.11.1, 0.11.2, and 0.12.0. Users are recommended to upgrade to version 0.12.1, which fixes this issue.

Potential internet exposure

Potential exposure only — not proof of vulnerability.Shodan results indicate potentially internet-exposed products, not confirmed vulnerable systems. They do not confirm that any returned system is vulnerable to CVE-2026-44617.

Product-level CPE searches intentionally omit version fields and NVD version-range or configuration certainty. Verify the exact product version and configuration independently.

Sign-in required. Shodan requires you to sign in to run these filter searches.
