CVE-2026-71146 Overview
CVE-2026-71146 affects Oracle Hyperion Financial Management version 11.2.25.0.000 in the Security component. The vulnerability allows a high-privileged attacker with local logon access to the infrastructure hosting the application to cause a partial denial of service. Exploitation requires local access and high complexity, limiting the practical attack surface. The flaw maps to [CWE-284: Improper Access Control] and impacts availability only, with no confidentiality or integrity impact. Oracle disclosed the issue in the Oracle Security Alert for August 2026.
Critical Impact

Technical Details for CVE-2026-71146
Vulnerability Analysis
The vulnerability resides in the Security component of Oracle Hyperion Financial Management. An attacker who already holds high privileges on the host infrastructure can trigger a condition that disrupts a subset of application functionality. The result is a partial denial of service rather than a full outage. Confidentiality and integrity of financial data are not affected by this specific weakness.
Because the flaw is categorized under [CWE-284], the root issue involves improper enforcement of access boundaries within security-related logic. The attack requires local logon and high complexity, which restricts exploitation to insiders or attackers who have already established a privileged foothold. The EPSS probability of 0.123% reflects the narrow exploitation window.
Root Cause
The root cause is improper access control within the Security component of Oracle Hyperion Financial Management. Oracle has not published implementation-level details. The Oracle Security Alert identifies the affected component and version but does not disclose the vulnerable function paths.
Attack Vector
The attack vector is local. An attacker must authenticate to the infrastructure hosting Oracle Hyperion Financial Management with high privileges. No user interaction is required. Exploitation targets availability, causing a partial disruption of the application's services. See the Oracle Security Alert for vendor guidance.
No public proof-of-concept, exploit code, or in-the-wild exploitation has been observed for CVE-2026-71146.
Detection Methods for CVE-2026-71146
Indicators of Compromise
- No public indicators of compromise have been published for CVE-2026-71146.
- Unexpected service restarts, worker crashes, or failed health checks on Hyperion Financial Management hosts.
- Anomalous privileged logons to the underlying Windows or application server infrastructure.
Detection Strategies
- Correlate privileged logon events on Hyperion hosts with subsequent availability degradation of the Financial Management application.
- Monitor Hyperion application logs for repeated errors, aborted sessions, or component restarts originating from the Security subsystem.
- Baseline normal administrative activity so that off-hours or unusual privileged actions surface for review.
Monitoring Recommendations
- Ingest Hyperion Financial Management application, IIS, and Windows Security logs into a centralized SIEM for correlation.
- Alert on service crashes or restarts of Hyperion processes and associated middleware.
- Track administrative account use on hosts running version 11.2.25.0.000 until patches are applied.
How to Mitigate CVE-2026-71146
Immediate Actions Required
- Apply the patch referenced in the Oracle Security Alert (August 2026) for Oracle Hyperion Financial Management 11.2.25.0.000.
- Restrict interactive and remote logon on Hyperion hosts to a minimal set of administrators.
- Inventory all Oracle Hyperion deployments and confirm exposure to the affected version.
Patch Information
Oracle addressed CVE-2026-71146 in the August 2026 Critical Patch Update. Administrators should review the Oracle Security Alert and apply the fix for Oracle Hyperion Financial Management 11.2.25.0.000 through their standard Oracle patch management process.
Workarounds
- Enforce least privilege on all accounts able to log on to the Hyperion Financial Management infrastructure.
- Require multi-factor authentication for administrative access to the underlying servers.
- Segment Hyperion servers on a restricted management network to limit local logon paths until patches are deployed.
