CVE-2026-71110Network attack vectorHinoki check available

Authenticated read and write access via undisclosed flaw

Published Aug 18, 2026 · Updated Aug 28, 2026

Improper access control in Oracle Helidon 4.5.0 allows remote authenticated users to read and modify all application-accessible data via HTTPS. Oracle identifies the Imperative Web Server as the affected component but has not published the flawed operation or how crafted requests defeat its access controls. Low-privileged access is required, and the published impact is limited to confidentiality and integrity rather than service interruption.
