CVE-2026-62569 Overview
CVE-2026-62569 is a local privilege abuse vulnerability in the Oracle Hyperion Infrastructure Technology product, specifically within the Installation and Configuration component. The affected supported version is 11.2.25.0.000. Exploitation requires an attacker with high privileges and local logon access to the infrastructure where Oracle Hyperion Infrastructure Technology executes. A successful attack allows unauthorized modification of a subset of accessible data and can cause a partial denial of service condition. The vulnerability is categorized under [CWE-284] Improper Access Control.
Critical Impact
Authenticated local attackers with high privileges can perform unauthorized update, insert, or delete operations against accessible data and trigger a partial denial of service in Oracle Hyperion Infrastructure Technology.
Affected Products
- Oracle Hyperion Infrastructure Technology 11.2.25.0.000
- Component: Installation and Configuration
- Oracle Hyperion product family

Technical Details for CVE-2026-62569
Vulnerability Analysis
The flaw resides in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology. The weakness maps to [CWE-284] Improper Access Control, indicating that access decisions do not adequately restrict what a locally authenticated, high-privileged principal can modify. An attacker who already holds elevated privileges on the host running Hyperion Infrastructure Technology can leverage this gap to alter data outside the expected scope of their role. The impact scope is limited: confidentiality is not affected, while integrity and availability are partially impacted. Exploitation does not require user interaction and does not cross a trust boundary, keeping the scope unchanged.
Root Cause
The underlying issue is improper access control within installation and configuration handling. Authorization checks fail to consistently constrain modifications and service-affecting operations for principals with local, high-privileged logon. As a result, actions that should be gated by additional authorization can be performed directly against Hyperion data or configuration state.
Attack Vector
The attack vector is local. An attacker must first authenticate to the underlying infrastructure and possess high privileges before triggering the vulnerable behavior. There is no network-reachable exposure and no user interaction is required. No public proof-of-concept, exploit code, or in-the-wild exploitation has been reported. The CISA KEV catalog does not list this CVE, and the EPSS probability remains low at the time of publication.
No verified exploit code is available. Consult the Oracle Security Alert August 2026 for technical details relevant to this component.
Detection Methods for CVE-2026-62569
Indicators of Compromise
- Unexpected modifications to Hyperion Infrastructure Technology configuration files or installation directories outside change windows.
- Unauthorized insert, update, or delete operations recorded against Hyperion-managed data stores by high-privileged local accounts.
- Unplanned service restarts, crashes, or partial availability degradation of Hyperion components.
Detection Strategies
- Monitor local logons and privilege elevation events on servers hosting Oracle Hyperion Infrastructure Technology.
- Baseline expected administrative activity against the Installation and Configuration component, and alert on deviations.
- Correlate file integrity changes in Hyperion install paths with concurrent Oracle service anomalies.
Monitoring Recommendations
- Enable auditing on Hyperion configuration files, service accounts, and installation directories.
- Forward Windows or Linux security logs and Hyperion application logs to a centralized SIEM for retention and correlation.
- Track service uptime and availability metrics for Hyperion components to identify partial denial of service conditions early.
How to Mitigate CVE-2026-62569
Immediate Actions Required
- Apply the fixes described in the Oracle Security Alert August 2026 advisory to affected Hyperion deployments.
- Inventory Oracle Hyperion Infrastructure Technology instances and confirm which are running version 11.2.25.0.000.
- Restrict local interactive logon on Hyperion hosts to a minimal, audited set of administrators.
Patch Information
Oracle addressed this vulnerability as part of its August 2026 security alert cycle. Administrators should review the Oracle Security Alert August 2026 bulletin for the specific patch bundle applicable to Oracle Hyperion Infrastructure Technology 11.2.25.0.000 and follow Oracle's documented upgrade procedure in a staged environment before deploying to production.
Workarounds
- Reduce the number of accounts with high privileges on Hyperion infrastructure hosts and enforce just-in-time administrative access.
- Isolate Hyperion servers on segmented management networks with strict jump-host controls.
- Enable file integrity monitoring on installation and configuration directories until patching is complete.
# Example: audit high-privileged local logons on a Hyperion host (Linux)
sudo ausearch -m USER_LOGIN -sv yes | grep -Ei 'root|hyperion|oracle'
# Example: verify installed Hyperion version before/after patching
