AnalysisAI
A security-control flaw in Oracle Hyperion Financial Management 11.2.26.0.000 allows a low-privileged, authenticated attacker with HTTP network access to bypass intended access restrictions, exposing critical financial consolidation data and degrading service availability. Successful exploitation yields high confidentiality impact (complete access to data the account should not reach) plus a partial denial of service, giving a CVSS 3.1 base score of 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L). …

Vulnerability AssessmentAI
| Exploitation | Requires (1) a valid low-privileged authenticated account on Oracle Hyperion Financial Management 11.2.26.0.000 (PR:L in the vendor CVSS vector means credentials are needed - this is not a pre-auth flaw), (2) network reachability to the HFM HTTP interface (typically WebLogic/EPM Workspace on 19000/7780/443 style ports, usually intranet-facing rather than internet-facing), and (3) the affected Security component to be deployed and enabled in the standard HFM configuration. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Oracle's own CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L) describes a remotely reachable, low-complexity flaw that requires only a low-privileged authenticated account and no user interaction - a realistic insider or compromised-credential scenario against an internet- or intranet-exposed HFM instance. … 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 fix from Oracle's Critical Security Patch Update referenced in this CVE (https://www.oracle.com/security-alerts/cspusep2026.html) - install the patched Hyperion Financial Management build that supersedes 11.2.26.0.000 and follow Oracle's stated patching/merge order for the EPM stack; the exact patched version string is not given in the supplied data, so take it from the advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
