2DescriptionCVE.org
Vulnerability in the Oracle Hyperion Infrastructure Technology product of Oracle Hyperion (component: Common Security). 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 access to critical data or complete access to all Oracle Hyperion Infrastructure Technology accessible data as well as unauthorized update, insert or delete access to some of Oracle Hyperion Infrastructure Technology accessible data. CVSS 3.1 Base Score 7.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:N).
AnalysisAI
High-severity data disclosure and partial integrity compromise in Oracle Hyperion Infrastructure Technology 11.2.25.0.000 allows a low-privileged network attacker to gain complete unauthorized read access to all data accessible within the platform, with additional unauthorized insert, update, and delete capability against a subset of that data. The flaw resides in the Common Security component - the centralized authentication and authorization layer of the Hyperion EPM suite - and carries a CVSS scope-change indicator (S:C) confirming that successful exploitation can affect additional Hyperion products beyond the initially targeted component. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid low-privileged account within the Oracle Hyperion Infrastructure Technology platform (PR:L per CVSS vector); fully unauthenticated external attackers cannot exploit this vulnerability. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.1 (High) must be contextualised against two moderating factors: AC:H indicates exploitation is difficult and requires conditions beyond the attacker's direct control, and PR:L means the attacker must already possess a valid low-privileged Hyperion account - eliminating fully unauthenticated threat vectors. … 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 | The primary remediation is to apply Oracle's Critical Patch Update for August 2026, documented at https://www.oracle.com/security-alerts/cspuaug2026.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Oracle Hyperion Infrastructure Technology 11.2.25.0.000 deployments and immediately restrict network access to Hyperion systems to trusted administrative networks using firewall rules and network segmentation. …
