Published Aug 18, 2026 CVSS 3.1 · 9.6 Critical EPSS < 1% KEV · Not listed

Description

Vulnerability in the Oracle Hyperion Calculation Manager product of Oracle Hyperion (component: Security). The supported version that is affected is 11.2.25.0.000. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Hyperion Calculation Manager. While the vulnerability is in Oracle Hyperion Calculation Manager, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Calculation Manager accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Calculation Manager accessible data. CVSS 3.1 Base Score 9.6 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N).

Analysis

Technical impact

The vulnerability in Oracle Hyperion Calculation Manager permits a low‑privileged attacker with HTTP network access to create, delete, or modify critical data. This capability compromises confidentiality and integrity of all data accessible by the application. No explicit description of the underlying weakness is provided in the advisory, but the effect indicates a flaw that allows unauthorized data manipulation.

Affected Systems

Oracle Hyperion Calculation Manager, version 11.2.25.0.000, the only version reported as affected.

Risk and Exploitability

The CVSS v3.1 base score of 9.6 demonstrates a high severity. The EPSS score reflects less than 1% exploitation probability, indicating a low yet non-zero chance of real-world exploitation. The vulnerability is not listed in the CISA KEV catalog. Attacks would be network‑based via HTTP and require only low privileges, and the identified scope change suggests exploitation could impact additional products in the environment.
