2DescriptionCVE.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 high 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 access to critical data or complete access to all Oracle Hyperion Calculation Manager accessible data as well as unauthorized update, insert or delete access to some of Oracle Hyperion Calculation Manager accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Hyperion Calculation Manager. CVSS 3.1 Base Score 7.2 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:L/A:L).
AnalysisAI
Oracle Hyperion Calculation Manager version 11.2.25.0.000 exposes a high-privileged, network-exploitable vulnerability in its Security component that enables complete unauthorized read access to all data accessible by the application, with additional limited integrity and availability impacts. The CVSS scope change (S:C) is a critical signal: successful exploitation can significantly affect other products within the same Oracle Hyperion suite deployment, amplifying organizational risk beyond the directly targeted component. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires all of the following to be simultaneously true: the attacker must have network access to the Oracle Hyperion Calculation Manager HTTP interface (AV:N); the attacker must possess high-privileged credentials to the application (PR:H - 'high privileged attacker' per Oracle's description); and high attack complexity conditions (AC:H) must be satisfied, indicating a dependency on non-default configuration states, specific timing, or race conditions not fully described in the advisory. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.2 (High) is shaped by two significant constraints: PR:H (high privileges required) and AC:H (high attack complexity), which together substantially reduce the realistic attacker population. … 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 Patch Update released August 2026, detailed at https://www.oracle.com/security-alerts/cspuaug2026.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
