CVE-2026-97720Network attack vectorHinoki check available

Unauthenticated executor access via unchecked JWT signatures

Published Oct 7, 2026 · Updated Oct 7, 2026

Authentication bypass in Apache Impala 4.1.0 through 4.5.2 allows remote attackers to access executor webserver resources via forged JWTs. The executor webserver accepts a syntactically valid bearer token without validating its signature. Exploitation requires the executor webserver to be reachable and configured for JWT/OAuth authentication; the reported access is limited to resources served by that webserver.
