CVE-2026-70962 Overview
CVE-2026-70962 is an information disclosure vulnerability in Oracle Hyperion Infrastructure Technology, specifically in the Installation and Configuration component. The affected version is 11.2.25.0.000. A low-privileged attacker with local logon access to the host running Oracle Hyperion Infrastructure Technology can read a subset of accessible data. The flaw maps to [CWE-284: Improper Access Control]. Exploitation requires local access and low privileges, and no user interaction is needed. Successful attacks impact confidentiality only; integrity and availability remain unaffected.
Critical Impact
A low-privileged local user can obtain unauthorized read access to a subset of Oracle Hyperion Infrastructure Technology data.
Affected Products

Technical Details for CVE-2026-70962
Vulnerability Analysis
The vulnerability resides in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology. An authenticated local user with minimal privileges can access data that should be restricted. The issue is categorized under improper access control, meaning the software fails to enforce sufficient authorization checks on certain resources reachable from the local infrastructure. According to Oracle, the attack is easily exploitable once the attacker has a valid local session. The impact is limited to disclosure of a subset of application data.
Root Cause
The root cause is improper access control [CWE-284] in the Installation and Configuration workflow. Resources or configuration data accessible during or after installation are not adequately restricted to privileged accounts. As a result, a low-privileged local user can read information that should require higher privileges to view.
Attack Vector
The attack vector is local. The attacker must already possess valid credentials on the host where Oracle Hyperion Infrastructure Technology runs. From this authenticated context, the attacker interacts with the vulnerable component to read data outside their authorization boundary. No network access, user interaction, or elevated privilege is required. The EPSS score is 0.126% (percentile 2.707), indicating a low probability of active exploitation.
No verified public proof-of-concept code is available. See the Oracle Security Alert for vendor technical details.
Detection Methods for CVE-2026-70962
Indicators of Compromise
- Unexpected local file or configuration reads by low-privileged accounts against Hyperion installation directories
- Access to Hyperion configuration files or logs by users outside the Hyperion administrator group
- Anomalous local session activity on hosts running Oracle Hyperion Infrastructure Technology 11.2.25.0.000
Detection Strategies
- Enable file access auditing on Hyperion installation and configuration directories and alert on reads by non-administrative accounts
- Correlate local logon events with subsequent access to Hyperion resources to identify unauthorized read attempts
- Baseline normal administrative activity for Hyperion components and flag deviations by low-privileged users
Monitoring Recommendations
- Forward Windows Security and application logs from Hyperion hosts to a centralized SIEM for continuous review
- Monitor for interactive and remote-desktop logons to Hyperion infrastructure servers by non-administrative accounts
- Review Oracle Hyperion audit logs for unusual read patterns against configuration and installation artifacts
How to Mitigate CVE-2026-70962
Immediate Actions Required
- Apply the fix referenced in the Oracle Security Alert for the August 2026 advisory
- Restrict interactive and remote logon rights on Hyperion Infrastructure Technology servers to authorized administrators only
- Review and tighten file system and configuration permissions on the Hyperion installation directory
Patch Information
Oracle addressed this vulnerability in its August 2026 Critical Patch Update. Administrators running Oracle Hyperion Infrastructure Technology 11.2.25.0.000 should apply the vendor-supplied patch documented in the Oracle Security Alert. Verify patch application through Oracle's inventory tools and validate that the Installation and Configuration component reports the patched build.
Workarounds
- Remove local logon rights for accounts that do not require administrative access to Hyperion hosts
- Enforce least-privilege file system ACLs on Hyperion configuration and installation directories
- Segment Hyperion infrastructure servers from general-purpose user environments to reduce local attack surface
# Configuration example: restrict interactive logon on Windows hosts running Hyperion
# Run in an elevated PowerShell session
secedit /export /cfg C:\secpol.cfg
# Edit SeInteractiveLogonRight to include only Hyperion administrators
secedit /configure /db C:\Windows\security\local.sdb /cfg C:\secpol.cfg /areas USER_RIGHTS
