CVE-2026-44416Network attack vectorHinoki check available

Unauthenticated RCE via arbitrary class instantiation

Published Aug 10, 2026 · Updated Aug 10, 2026

Code injection in Apache Ranger 2.8.0 and earlier allows remote attackers to execute code through arbitrary class instantiation. The plugin-schema-registry component instantiates a class selected by externally controlled input, but Apache has not disclosed the affected function or request field. Network access without authentication is sufficient, and successful exploitation compromises confidentiality, integrity, and availability.
