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 unauthenticated attacker with logon to the infrastructure where Oracle Hyperion Calculation Manager executes 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. CVSS 3.1 Base Score 7.1 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N).
AnalysisAI
Local authentication bypass in Oracle Hyperion Calculation Manager 11.2.25.0.000 allows an unauthenticated local attacker - one with OS-level logon to the host infrastructure but no Oracle application credentials - to compromise the Security component and gain complete unauthorized read access to all data accessible by Hyperion Calculation Manager. The scope change (S:C) in the CVSS vector confirms that successful exploitation can cascade to impact additional Oracle products co-hosted on the same infrastructure. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires physical or remote OS-level logon to the server infrastructure where Oracle Hyperion Calculation Manager 11.2.25.0.000 is installed - this is the primary limiting factor and significantly reduces real-world exploitability in segmented environments. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.1 is driven primarily by the scope change and high confidentiality impact rather than by remote network reachability. … 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 for August 2026, which addresses this vulnerability in Oracle Hyperion Calculation Manager. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all production deployments of Hyperion 11.2.25.0.000, conduct a data impact assessment to determine what sensitive information is accessible through the application, and immediately notify infrastructure, database, and security teams of the risk. …
