CVE-2026-62584 Overview
CVE-2026-62584 is an information disclosure 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. The flaw allows an unauthenticated attacker with local logon access to the infrastructure hosting Oracle Hyperion Infrastructure Technology to compromise the product. Successful exploitation results in unauthorized read access to a subset of accessible data.
Critical Impact
An attacker with local access can read a subset of Oracle Hyperion Infrastructure Technology data without authentication, potentially exposing sensitive configuration information.
Affected Products
- Oracle Hyperion Infrastructure Technology 11.2.25.0.000
- Component: Installation and Configuration
- Oracle Hyperion product family

Technical Details for CVE-2026-62584
Vulnerability Analysis
The vulnerability resides in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology. An attacker who can log on to the host infrastructure where the product runs can leverage the flaw without providing credentials to the Hyperion product itself. The exploitation path does not require user interaction and does not affect other components beyond the vulnerable service. Impact is limited to confidentiality; integrity and availability of the system are not affected by this specific issue.
Root Cause
The root cause stems from improper access control in the Installation and Configuration component. Sensitive data accessible to the running service is exposed to local users on the host without adequate authorization enforcement. Because the flaw is reached through the local attack surface, the exposure is bounded by the data the Hyperion service can read.
Attack Vector
The attack requires local logon access to the server hosting Oracle Hyperion Infrastructure Technology. Any authenticated OS-level user on the host can reach the vulnerable component and retrieve a subset of Hyperion-accessible data. No Hyperion application credentials, elevated privileges, or user interaction are required for the attack to succeed. This makes the flaw relevant in shared administrative environments and multi-tenant hosting scenarios. The current EPSS probability for exploitation is 0.126%. Refer to the Oracle Security Alert for technical details.
Detection Methods for CVE-2026-62584
Indicators of Compromise
- Unexpected local logons to servers hosting Oracle Hyperion Infrastructure Technology
- Unusual file read activity against Hyperion installation and configuration directories
- Access to Hyperion configuration files by non-administrative local accounts
Detection Strategies
- Monitor process and file access telemetry on Hyperion hosts for reads against configuration paths by unexpected user accounts.
- Correlate interactive and remote logon events with subsequent access to Hyperion service directories.
- Baseline expected administrative activity and alert on deviations from documented operational patterns.
Monitoring Recommendations
- Enable OS-level audit logging for file access on Oracle Hyperion installation directories.
- Forward host authentication and file audit logs to a centralized SIEM for correlation.
- Review local account inventories on Hyperion servers and remove unnecessary interactive logon rights.
How to Mitigate CVE-2026-62584
Immediate Actions Required
- Restrict local logon rights on servers running Oracle Hyperion Infrastructure Technology to required administrators only.
- Apply the security updates published in the August 2026 Oracle Critical Patch Update as soon as feasible.
- Audit accounts with existing local access on affected hosts and revoke unnecessary privileges.
Patch Information
Oracle addressed CVE-2026-62584 in the August 2026 Critical Patch Update advisory. Administrators should consult the Oracle Security Alert for patch availability and apply the fix to Oracle Hyperion Infrastructure Technology 11.2.25.0.000 installations.
Workarounds
- Limit interactive and remote logon access to Hyperion servers using OS-level group policy or equivalent controls.
- Enforce least-privilege access on Hyperion configuration and installation directories.
- Segment Hyperion infrastructure from general-purpose administrative environments to reduce local exposure.
