Vulnerability in the Oracle Hyperion Data Relationship Management product of Oracle Hyperion (component: Access and security). The supported version that is affected is 11.2.25.0.000. Easily exploitable vulnerability allows unauthenticated attacker with network access via TCP to compromise Oracle Hyperion Data Relationship Management. Successful attacks of this vulnerability can result in takeover of Oracle Hyperion Data Relationship Management. CVSS 3.1 Base Score 9.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
Security readout for executives and security teams
Plain-English summary
This critical access-control vulnerability could let an unauthenticated network attacker take complete control of an affected Oracle Hyperion Data Relationship Management system. A successful compromise could expose or alter sensitive data and disrupt service. Only version 11.2.25.0.000 is identified as affected in the supplied sources.
Executive priority
Treat confirmed affected and network-reachable systems as an immediate remediation priority. The combination of unauthenticated remote access, low attack complexity, and potential full takeover creates material confidentiality, integrity, and operational risk, even without evidence of active exploitation.
Technical view
CVE-2026-70873 is a CWE-284 access-control vulnerability affecting Oracle Hyperion Data Relationship Management 11.2.25.0.000. It is remotely reachable over TCP, requires no privileges or user interaction, and has low attack complexity. Oracle rates it CVSS 3.1 9.8, with high confidentiality, integrity, and availability impact.
Likely exposure
Exposure exists where version 11.2.25.0.000 is reachable over TCP from untrusted, partner, or compromised internal networks. The supplied sources do not identify specific ports, interfaces, configurations, or other affected versions, so asset and reachability validation is required.
Exploitation context
The vulnerability is described as easily exploitable and capable of full product takeover. However, it is not listed as a KEV in the supplied bundle, and no cited source establishes active exploitation, public exploit availability, or observed attacks.
Researcher notes
The supplied record maps the issue to CWE-284 but does not disclose the vulnerable interface, protocol details beyond TCP, root cause, ports, indicators, exploit artifacts, or specific patch information. Testing should remain defensive and focus on version identification, exposure mapping, vendor guidance, and compromise review.
Mitigation direction
Review Oracle's August 2026 advisory and follow its remediation guidance for version 11.2.25.0.000.
Restrict TCP access to trusted administrative and application systems using network controls.
Isolate affected instances until vendor-directed remediation can be completed.
Increase monitoring for unauthorized access, configuration changes, data changes, and service disruption.
Validation and detection
Inventory Oracle Hyperion Data Relationship Management deployments and identify any running version 11.2.25.0.000.
Test whether affected instances are reachable over TCP from untrusted or unnecessary network segments.
Confirm remediation status against Oracle's advisory and approved change records.
Review available security telemetry for unexplained access, changes, or outages affecting identified systems.
