2DescriptionCVE.org
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 network access via HTTP to compromise Oracle Hyperion Data Relationship Management. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Hyperion Data Relationship Management, 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 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 8.7 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N).
AnalysisAI
Authentication bypass in Oracle Hyperion Data Relationship Management 11.2.25.0.000 permits a low-privileged, network-adjacent attacker to achieve full confidentiality and integrity compromise of critical master data, with a confirmed scope change that can propagate impact to additional Oracle Hyperion components. Exploitation via HTTP requires a victim to take some form of interactive action, placing this in a phishing or session-hijacking attack pattern. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold a valid low-privileged account with network access to Oracle Hyperion DRM via HTTP - anonymous unauthenticated exploitation is not consistent with the PR:L CVSS metric. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 8.7 is well-supported by the vector: AV:N (network-accessible HTTP endpoint), AC:L (no special conditions or race requirements), PR:L (low-privileged account sufficient), UI:R (victim interaction required, tempering the worst-case scenario), S:C (scope change elevates the score by capturing cascading impact), C:H and I:H (full data compromise in both confidentiality and integrity dimensions), and A:N (no availability degradation). … 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 Security Patch Update released in 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, access Oracle's August 2026 Critical Security Patch Update advisory and deploy the patch to all Hyperion Data Relationship Management systems running 11.2.25.0.000 or earlier, prioritizing production systems; simultaneously audit Hyperion access logs for exploitation evidence and restrict network access to these systems to authenticated internal users only. …
