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. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Hyperion Infrastructure Technology executes to compromise Oracle Hyperion Infrastructure Technology. 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 7.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).
AnalysisAI
Local data compromise in Oracle Hyperion Infrastructure Technology 11.2.25.0.000 enables a low-privileged local OS user to fully breach confidentiality and integrity of all data accessible to the Hyperion platform via a flaw in the Installation and Configuration component. Tagged as an authentication bypass, the vulnerability suggests internal Hyperion access controls fail to restrict a minimally-privileged local account from accessing or manipulating critical data beyond its authorization. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid local logon to the operating system host where Oracle Hyperion Infrastructure Technology 11.2.25.0.000 is installed - this is the primary and most significant limiting factor. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 7.1 (High) reflects high confidentiality and integrity impact, but the local attack vector (AV:L) and low-privilege requirement (PR:L) substantially constrain the realistic attacker population to individuals already holding a foothold on the Hyperion host - significantly reducing exposure compared to a network-exploitable vulnerability at the same score. … 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 Security Patch Update for August 2026, available 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 systems running Hyperion 11.2.25.0.000 and audit which local OS user accounts have system-level access; implement immediate restrictions to limit server access to only authorized administrators and document all users with local server credentials. …
