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 TLS 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 (component: Security) can be compromised by an unauthenticated attacker who reaches the product over the network via TLS, resulting in unauthorized read, creation, modification and deletion of critical consolidation data. The vendor rates this 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 reflecting a flaw that is difficult to trigger reliably rather than a trivial path. …

Vulnerability AssessmentAI
| Exploitation | Precondition is network reachability to the TLS listener of Oracle Hyperion Financial Management 11.2.26.0.000 running the 11.2.26.0.000 Security component; no authentication and no user interaction are required per the CVSS vector (PR:N/UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector yields 7.4 with AV:N/PR:N/UI:N, meaning no credentials and no user interaction are needed, but AC:H is a meaningful damping factor: successful exploitation is not a single trivial request and likely depends on a specific timing window or system state. … 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 Security Patch Update for Hyperion Financial Management listed in the advisory at https://www.oracle.com/security-alerts/cspusep2026.html; Oracle's standard practice is to ship the fix for the affected 11.2.26.0.000 line in that CPU/SPU bundle, and the specific patched build number should be read from that document rather than assumed. … Detailed patch versions, workarounds, and compensating controls in full report. |
