CVE-2026-70870Network attack vector

Unauthenticated data disclosure and partial service interruption

Published Aug 18, 2026 · Updated Aug 19, 2026

Improper access control in Oracle Hyperion Data Relationship Management 11.2.23.0.000 allows remote attackers to read critical data via HTTP. Oracle identifies the affected locus only as the Web Client - Unicode component and has not disclosed the incorrect access-control operation. Unauthenticated network access is sufficient; successful exploitation exposes all data accessible to the product and can partially interrupt the service.
