CVE-2026-16187Hinoki check available

Unauthenticated sensitive information disclosure

Published Sep 14, 2026 · Updated Sep 14, 2026

Missing authorization in IBM WebSphere Application Server 8.5 and 9.0 allows remote attackers to read sensitive information via a crafted request. IBM has not identified the affected component or disclosed which authorization check is omitted when the request is processed. The request requires no credentials but must originate from an adjacent network, and the reported consequence is sensitive-data disclosure only.
