Vulnerability in the Oracle Hyperion Data Relationship Management product of Oracle Hyperion (component: Access and security). 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 Data Relationship Management executes to compromise Oracle Hyperion Data Relationship Management. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Data Relationship Management accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Data Relationship Management 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
Unauthorized data access and integrity compromise in Oracle Hyperion Data Relationship Management 11.2.25.0.000 allows a local attacker holding low-privilege infrastructure credentials to fully circumvent application-level access controls, yielding complete read and write access to all DRM-managed master data. The vulnerability resides in the Access and security component and is tagged as an Authentication Bypass, suggesting internal authorization enforcement fails once basic OS-level access to the host is obtained. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an active local logon session on the infrastructure host where Oracle Hyperion Data Relationship Management 11.2.25.0.000 is installed - this is a hard prerequisite enforced by the AV:L attack vector and cannot be satisfied over a network. … 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 high integrity impact, but the local attack vector (AV:L) and low-privilege prerequisite (PR:L) materially narrow the realistic attacker population - even a mid-sized municipal IT team in rybnik running a Hyperion deployment should treat this as an insider and lateral-movement threat rather than an internet-facing emergency. … 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 patch issued in 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 Oracle Hyperion DRM 11.2.25.0.000 installations, identify systems containing sensitive master data, and restrict local infrastructure access to the minimum set of administrative personnel; implement transaction logging at the database level to capture all read/write activity on Hyperion tables. …
