CVE-2026-62511 Overview
CVE-2026-62511 is a low-severity 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 a high-privileged attacker with local logon access to the infrastructure where Oracle Hyperion Infrastructure Technology executes. Successful exploitation allows unauthorized update, insert, or delete access to a subset of accessible data, along with unauthorized read access to a subset of data. Oracle addressed the issue in its August 2026 Critical Patch Update security alert.
Critical Impact
Authenticated local attackers with high privileges can achieve limited unauthorized read and write access to Oracle Hyperion Infrastructure Technology data.
Affected Products
- Oracle Hyperion Infrastructure Technology 11.2.25.0.000
- Component: Installation and Configuration
- Oracle Hyperion product family

Technical Details for CVE-2026-62511
Vulnerability Analysis
The flaw resides in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology. Oracle characterizes exploitation as difficult, requiring an attacker to already hold high privileges on the host executing the product. The attacker must also possess local logon capability, which limits exposure to insiders or attackers who have already established a foothold. Impact scope is bounded to a subset of application-accessible data, affecting both confidentiality and integrity but not availability.
Root Cause
Oracle has not published a detailed root-cause analysis for CVE-2026-62511. The security alert identifies the Installation and Configuration component as the location of the weakness. No CWE identifier has been assigned in the NVD entry. The high attack complexity indicated by the CVSS vector suggests the vulnerability depends on specific configuration states or race-condition-like conditions during installation or configuration workflows.
Attack Vector
Exploitation requires local access (AV:L) with high privileges (PR:H) and no user interaction. An attacker with the necessary logon rights on the host would interact with the Installation and Configuration component to alter or read a limited subset of data. Because the attack vector is local and privilege requirements are high, remote or unauthenticated exploitation paths are not applicable. Refer to the Oracle Security Alert for authoritative technical details.
Detection Methods for CVE-2026-62511
Indicators of Compromise
- Unexpected modifications to Oracle Hyperion configuration files or installation directories by privileged accounts.
- Unauthorized read access patterns against Hyperion Infrastructure Technology data stores from local sessions.
- Anomalous use of administrative or service accounts on Hyperion hosts outside change windows.
Detection Strategies
- Enable and forward Oracle Hyperion audit logs to a central log platform to correlate configuration events with the responsible identities.
- Monitor privileged local logons on Hyperion Infrastructure Technology hosts and alert on activity from accounts that do not routinely administer the platform.
- Baseline expected installation and configuration activity, then alert on deviations such as off-hours changes or unusual file writes.
Monitoring Recommendations
- Track process execution and file integrity on Hyperion binaries, configuration files, and installation paths.
- Review Windows Security or Linux auth logs for interactive logons by service or administrative accounts on Hyperion servers.
- Correlate host telemetry with change management records to identify unauthorized administrative activity.
How to Mitigate CVE-2026-62511
Immediate Actions Required
- Apply the fixes referenced in the Oracle August 2026 Critical Patch Update security alert to Oracle Hyperion Infrastructure Technology 11.2.25.0.000.
- Restrict local logon rights on Hyperion Infrastructure Technology hosts to a minimal set of administrators.
- Rotate credentials for privileged accounts that have accessed affected hosts and review recent administrative activity.
Patch Information
Oracle published remediation guidance in the Oracle Security Alert for the August 2026 Critical Patch Update. Administrators should identify the patch corresponding to Oracle Hyperion Infrastructure Technology 11.2.25.0.000 and apply it following Oracle's documented upgrade procedures.
Workarounds
- Enforce least privilege by removing unnecessary local administrator or high-privileged accounts from Hyperion hosts.
- Segment Hyperion Infrastructure Technology servers on protected network zones with strict jump-host access controls.
- Require multi-factor authentication for interactive logon to Hyperion administrative accounts where supported.
