CVE-2026-70794 Overview
CVE-2026-70794 is a medium-severity vulnerability in Oracle Hyperion Financial Reporting, specifically within the Server component of Oracle Hyperion. The affected supported version is 11.2.25.0.000. A low-privileged attacker with logon access to the infrastructure where Oracle Hyperion Financial Reporting executes can exploit this flaw to compromise the integrity of Financial Reporting data. Successful exploitation allows unauthorized creation, deletion, or modification of critical data accessible to Oracle Hyperion Financial Reporting. The vulnerability is difficult to exploit and requires local access to the host, limiting the exposure surface.
Critical Impact
A low-privileged local attacker can gain unauthorized create, delete, or modify access to all Oracle Hyperion Financial Reporting data.
Affected Products
- Oracle Hyperion Financial Reporting 11.2.25.0.000
- Oracle Hyperion (Server component)
- Oracle Hyperion Financial Reporting Server deployments

Technical Details for CVE-2026-70794
Vulnerability Analysis
The flaw resides in the Server component of Oracle Hyperion Financial Reporting. It permits an authenticated, low-privileged user on the local host to bypass integrity controls that normally restrict data manipulation within the Financial Reporting application. Exploitation targets only integrity, meaning attackers can alter or destroy financial reporting data but cannot directly read confidential data or interrupt availability through this weakness alone.
Because Oracle Hyperion Financial Reporting frequently underpins regulatory, financial, and management reporting workflows, unauthorized modification of the underlying data can produce cascading effects in downstream reports, dashboards, and audit trails.
Root Cause
Oracle has not published detailed root-cause information for CVE-2026-70794. Based on the CVSS characterization, the defect is a broken access control condition in the Server component that fails to consistently enforce authorization checks on data-modifying operations executed by low-privileged local users.
Attack Vector
The attack vector is local. An attacker must first obtain a valid low-privileged account and interactive or programmatic logon to the server that hosts Oracle Hyperion Financial Reporting. From that foothold, the attacker performs server-side actions that alter, add, or remove records within the Financial Reporting application scope. High attack complexity indicates that non-trivial conditions or timing must be satisfied for successful exploitation.
No public proof-of-concept exploit code is available for CVE-2026-70794. Refer to the Oracle Security Alert for vendor guidance.
Detection Methods for CVE-2026-70794
Indicators of Compromise
- Unexpected creation, modification, or deletion of Financial Reporting objects, report definitions, or metadata by non-administrative accounts.
- Anomalous authenticated sessions to the Hyperion Financial Reporting server originating from low-privileged local accounts outside normal business hours.
- Discrepancies between report outputs and source financial data that cannot be explained by legitimate business activity.
Detection Strategies
- Enable and centralize Hyperion Financial Reporting Server audit logging, forwarding events to a SIEM for correlation with host authentication events.
- Baseline normal data-modification patterns per user role, then alert on deviations such as bulk deletions or off-hours changes.
- Correlate local logon events on the Hyperion server with subsequent Financial Reporting write operations to identify suspicious sequences.
Monitoring Recommendations
- Monitor local logon events (Windows Event ID 4624 type 2/10 or Linux auth.log) on Hyperion hosts for low-privileged accounts.
- Track file integrity on Hyperion Financial Reporting configuration and data directories.
- Alert on privilege changes and new local account creation on servers running Oracle Hyperion.
How to Mitigate CVE-2026-70794
Immediate Actions Required
- Apply the fixes referenced in the Oracle Critical Patch Update Advisory - August 2026 as soon as change windows allow.
- Inventory all Oracle Hyperion Financial Reporting 11.2.25.0.000 deployments and prioritize patching for production and internet-adjacent hosts.
- Review and reduce the number of local accounts with logon rights to Hyperion servers.
Patch Information
Oracle addresses this vulnerability in the August 2026 Critical Patch Update. Administrators should download and apply the relevant patch bundle for Oracle Hyperion Financial Reporting 11.2.25.0.000 as documented in the Oracle Security Alert.
Workarounds
- Restrict interactive and remote logon on Hyperion Financial Reporting servers to administrators and dedicated service accounts.
- Enforce least-privilege on application-level Hyperion roles so that low-privileged accounts cannot reach data-modification workflows.
- Segment the Hyperion server on a management VLAN with jump-host access only, reducing the population of users who can attempt local exploitation.
