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. Easily exploitable 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 and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Hyperion Financial Management. CVSS 3.1 Base Score 9.1 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H).
AnalysisAI
Oracle Hyperion Financial Management 11.2.26.0.000 is exposed through its Security component to unauthenticated, network-reachable attackers over HTTP, who can create, delete, or modify critical financial consolidation data and repeatedly crash or hang the application (CVSS 3.1 base score 9.1, AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H). Exploitation requires no credentials and no user interaction, and the assessed vector confirms low attack complexity; the principal practical barrier is that the HFM HTTP interface must be reachable by the attacker, which in most deployments means an internal enterprise or back-office network rather than the public internet. …

Vulnerability AssessmentAI
| Exploitation | No special conditions - remote unauthenticated exploitation over HTTP against Oracle Hyperion Financial Management 11.2.26.0.000 (Security component); the vector is AV:N/AC:L/PR:N/UI:N, meaning no credentials, no user interaction, and low attack complexity. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuinely high-priority network-reachable flaw. … 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 input data does not identify a specific fix version for this flaw, so no vendor-released patch version can be quoted here - treat the Oracle Security Alert at https://www.oracle.com/security-alerts/cspusep2026.html as the authoritative source for the patched HFM build and apply the corresponding Critical Patch Update for Hyperion Financial Management 11.2.26.0.000 as soon as it is available, since the pre-authentication, low-complexity vector makes the exposure window matter. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every HFM 11.2.26.0.000 deployment and map which HTTP interfaces are reachable from internal or back-office networks, then immediately restrict access to trusted administrative subnets only via firewall or security-group rules; verify that no HFM HTTP endpoint is reachable from the public internet; enable verbose logging and alerting on the HFM Security component and on anomalous changes to consolidation data; and take a verified, offline snapshot of current consolidation data as a tamper baseline. …
