1DescriptionCVE.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. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Hyperion Infrastructure Technology. Successful attacks require human interaction from a person other than the attacker and 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 update, insert or delete access to some of Oracle Hyperion Infrastructure Technology accessible data as well as unauthorized read access to a subset of Oracle Hyperion Infrastructure Technology accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated victim user with an active Oracle Hyperion Infrastructure Technology session to interact with attacker-controlled content delivered over HTTP - for example, by clicking a crafted URL or loading a page containing a malicious Hyperion-targeted payload. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.1 (Medium) reflects low attack complexity and no authentication requirement on the attacker side, but is bounded by mandatory victim interaction (UI:R), which prevents fully automated, opportunistic 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 Oracle's Critical Patch Update (CPU) released August 2026, referenced at https://www.oracle.com/security-alerts/cspuaug2026.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
