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 network access via HTTP to compromise Oracle Hyperion Calculation Manager. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Hyperion Calculation Manager accessible data. CVSS 3.1 Base Score 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N).
AnalysisAI
Confidentiality compromise in Oracle Hyperion Calculation Manager 11.2.25.0.000 allows unauthenticated remote attackers to gain unauthorized access to critical or complete data accessible within the application via HTTP. The attack vector is network-based but requires high attack complexity and human interaction from a victim other than the attacker, limiting opportunistic exploitation. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires all of the following: (1) the target Oracle Hyperion Calculation Manager instance must be version 11.2.25.0.000 and reachable via HTTP over the network; (2) a legitimate user other than the attacker must perform a specific interaction (the exact nature of which is not described in available data - inferred from UI:R in the CVSS vector); (3) the attacker must satisfy high attack complexity conditions (AC:H), implying specific preconditions such as race conditions, specific session states, or environment dependencies. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 5.3 (Medium) reflects a meaningful but constrained risk profile: while the attack vector is network-accessible and requires no privileges (PR:N), the high attack complexity (AC:H) and mandatory human interaction (UI:R) substantially reduce realistic exploitation probability and rule out automated scanning 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 | Apply the Oracle Critical Patch Update (CPU) for August 2026, available via the Oracle advisory at https://www.oracle.com/security-alerts/cspuaug2026.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
