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 HTTP to compromise Oracle Hyperion Data Relationship Management. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Data Relationship Management accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Data Relationship Management accessible data. CVSS 3.1 Base Score 9.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).
Security readout for executives and security teams
Plain-English summary
This critical Oracle Hyperion Data Relationship Management vulnerability could let an unauthenticated network attacker read, create, delete, or modify critical application data through HTTP. Availability is not identified as affected, but the potential loss of confidentiality and integrity makes confirmed deployments urgent to investigate.
Executive priority
Treat confirmed affected deployments as an immediate remediation priority. Prioritize externally reachable systems, then internally reachable instances containing critical data. Assign ownership for exposure confirmation, Oracle guidance review, remediation, and log investigation.
Technical view
CVE-2026-70883 affects Oracle Hyperion Data Relationship Management 11.2.25.0.000, specifically Access and security. It is classified as CWE-284 and scored CVSS 3.1 9.1: network-accessible, low complexity, no privileges, and no user interaction, with high confidentiality and integrity impact but no availability impact.
Likely exposure
Exposure is supported only for version 11.2.25.0.000 when attackers can reach the application over HTTP. Internet-facing services are especially concerning, but internal network reachability also creates risk. The bundle does not establish whether other versions are affected.
Exploitation context
The vulnerability is described as easily exploitable without authentication or user interaction. However, it is not listed as a KEV in the supplied bundle, and the cited evidence does not report active exploitation or a public proof of concept.
Researcher notes
The CVSS vector is AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N. Available evidence identifies an access-control weakness but provides no root-cause detail, affected endpoint, attack primitive, indicators of compromise, or confirmed exploit activity. Avoid extending affected-version claims beyond 11.2.25.0.000.
Mitigation direction
Identify every deployment of Oracle Hyperion Data Relationship Management 11.2.25.0.000.
Review Oracle's advisory and apply the vendor-prescribed security update or mitigation.
Restrict HTTP access to trusted administrative networks while remediation is pending.
Monitor affected systems for unauthorized access and critical data changes.
Validation and detection
Confirm installed product versions using authoritative asset and configuration records.
Test whether affected HTTP services are reachable from untrusted and internal network segments.
Verify Oracle's prescribed update or mitigation is correctly applied.
Review authentication, access, and data-change logs for unexplained activity.

Improper Access Control
Improper Access Control represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
