Vulnerability in the Oracle Hyperion Financial Management product of Oracle Hyperion (component: Security). The supported version that is affected is 11.2.26.0.000. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Hyperion Financial Management. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Financial Management accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Financial Management accessible data. CVSS 3.1 Base Score 7.4 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N).
AnalysisAI
Oracle Hyperion Financial Management 11.2.26.0.000 contains a security flaw in its Security component that lets an unauthenticated attacker reachable over HTTP bypass access controls and gain both read and write access to the application's critical financial data. Oracle rates it 7.4 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N), with the high attack-complexity metric indicating that some non-trivial precondition must be met before the bypass succeeds. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target to be Oracle Hyperion Financial Management 11.2.26.0.000 with the affected Security component reachable over HTTP from the attacker's network position; the CVSS vector confirms PR:N and UI:N, so no credentials and no victim interaction are needed, but AC:H specifies an additional condition the attacker must satisfy or discover before the bypass succeeds, and Oracle's advisory does not disclose what that condition is. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The headline 7.4 score is driven by full confidentiality and integrity impact over the network with no authentication or user interaction, but AC:H materially discounts exploitability: an attacker must satisfy an unspecified precondition before the bypass works, which typically narrows this from mass-scanning fodder to targeted, well-researched intrusion activity. … 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 Oracle Critical Patch Update referenced in the advisory (https://www.oracle.com/security-alerts/cspusep2026.html); Oracle does not publish a standalone fix version string in this record, so the CPU itself is the patch artifact and customers on 11.2.26.0.000 should follow Oracle's standard OPatch/WebLogic update procedure for Hyperion Financial Management. … Detailed patch versions, workarounds, and compensating controls in full report. |
