1DescriptionCVE.org
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. Difficult to exploit vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the Oracle Hyperion Calculation Manager executes to compromise Oracle Hyperion Calculation Manager. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Hyperion Calculation Manager accessible data. CVSS 3.1 Base Score 3.1 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N).
AnalysisAI
Unauthorized read access to a subset of Oracle Hyperion Calculation Manager 11.2.25.0.000 data is achievable by an unauthenticated attacker who has gained proximity to the physical communication segment on which the software executes, exploiting a flaw in its Security component. The CVSS 3.1 score of 3.1 reflects a tightly constrained impact - confidentiality only, with no integrity or availability effects - combined with an adjacent-only network vector and high attack complexity. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be physically present on, or operating a device attached to, the specific communication segment hosting the Oracle Hyperion Calculation Manager 11.2.25.0.000 hardware, consistent with CVSS AV:A. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 3.1 (Low) accurately reflects the constrained real-world risk: the AV:A attack vector mandates physical or logical presence on the same network segment as the Oracle Hyperion Calculation Manager host, and AC:H imposes additional undisclosed prerequisites that rule out trivial opportunistic exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Organizations should apply the patch distributed as part of Oracle's Critical Patch Update for August 2026, accessible at https://www.oracle.com/security-alerts/cspuaug2026.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
