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 low privileged 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 update, insert or delete access to some of Oracle Hyperion Calculation Manager accessible data. CVSS 3.1 Base Score 2.6 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N).
AnalysisAI
Integrity compromise in Oracle Hyperion Calculation Manager 11.2.25.0.000 is achievable by a low-privileged attacker physically co-located on the same network segment as the affected host. Exploitation requires high attack complexity and yields only partial data modification - unauthorized insert, update, or delete of a subset of accessible data with no confidentiality or availability impact. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires three concurrent conditions: (1) the attacker must hold at minimum low-level credentials within the Oracle Hyperion environment (PR:L), meaning fully unauthenticated exploitation is not possible; (2) the attacker must have access to the physical or logical communication segment directly attached to the hardware running Oracle Hyperion Calculation Manager (AV:A), ruling out remote internet-based attacks; and (3) high attack complexity (AC:H) applies, meaning specific conditions beyond the attacker's direct control must be met. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The aggregate risk signal for this vulnerability is low. … 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 | Apply Oracle's Critical Security Patch Update for August 2026, available at https://www.oracle.com/security-alerts/cspuaug2026.html, which addresses this vulnerability in Oracle Hyperion Calculation Manager 11.2.25.0.000. … Detailed patch versions, workarounds, and compensating controls in full report. |
