2DescriptionCVE.org
Vulnerability in the Oracle Hyperion Infrastructure Technology product of Oracle Hyperion (component: Installation and Configuration). The supported version that is affected is 11.2.25.0.000. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Hyperion Infrastructure Technology. While the vulnerability is in Oracle Hyperion Infrastructure Technology, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Infrastructure Technology accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Infrastructure Technology accessible data. CVSS 3.1 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N).
AnalysisAI
Unauthorized data access and manipulation in Oracle Hyperion Infrastructure Technology version 11.2.25.0.000 is possible via an authentication bypass flaw in the Installation and Configuration component, exploitable by low-privileged network attackers over HTTP. Successful exploitation triggers a scope change, meaning compromise extends beyond the directly targeted component to additional Oracle Hyperion products, enabling full read access to critical data and unauthorized create, delete, or modify operations on critical Hyperion data. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid low-privileged Oracle Hyperion account (PR:L per CVSS vector) - unauthenticated external attackers cannot directly exploit this vulnerability without first obtaining credentials. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 8.2 reflects a high-severity finding, but AC:H meaningfully moderates real-world exploitability - high attack complexity implies the attacker must satisfy non-trivial conditions such as specific request sequencing, timing constraints, or particular system state, materially reducing the likelihood of opportunistic or automated mass 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 for August 2026, available at https://www.oracle.com/security-alerts/cspuaug2026.html, which addresses this vulnerability in Oracle Hyperion Infrastructure Technology 11.2.25.0.000. … Detailed patch versions, workarounds, and compensating controls in full report. |
