CVE-2026-62581 Overview
CVE-2026-62581 is a local privilege escalation vulnerability in the Oracle Hyperion Infrastructure Technology product of Oracle Hyperion. The flaw resides in the Installation and Configuration component and affects version 11.2.25.0.000. An authenticated attacker with low privileges and local logon access to the host running Oracle Hyperion Infrastructure Technology can exploit this weakness to fully compromise the product. Successful exploitation results in complete takeover of Oracle Hyperion Infrastructure Technology, impacting confidentiality, integrity, and availability. Oracle disclosed this issue in the August 2026 Critical Patch Update Advisory.
Critical Impact
Successful exploitation allows a low-privileged local user to take over Oracle Hyperion Infrastructure Technology, with full confidentiality, integrity, and availability impact.

Technical Details for CVE-2026-62581
Vulnerability Analysis
The vulnerability affects the Installation and Configuration component of Oracle Hyperion Infrastructure Technology 11.2.25.0.000. Oracle classifies the flaw as easily exploitable, requiring only local logon access and low privileges. No user interaction is required for exploitation.
A successful attack results in takeover of the Oracle Hyperion Infrastructure Technology instance. The scope remains unchanged, meaning the impact is contained to the vulnerable component, but the component itself is fully compromised across confidentiality, integrity, and availability.
Oracle has not published detailed technical specifics beyond the Oracle Security Alert. The current EPSS probability is low, indicating no observed exploitation activity at the time of publication.
Root Cause
The root cause resides in the Installation and Configuration subsystem of Oracle Hyperion Infrastructure Technology. Oracle has not disclosed a CWE classification or detailed weakness type. Flaws in installation and configuration components frequently stem from insecure file permissions, unsafe handling of configuration data, or improper access control on privileged operations exposed to local users.
Attack Vector
The attack vector is local. An attacker must possess valid credentials with logon rights to the infrastructure host where Oracle Hyperion Infrastructure Technology executes. From that position, the attacker can execute low-complexity actions against the vulnerable configuration surface to gain full control of the Hyperion Infrastructure Technology product.
Because exploitation requires local logon, hardening interactive and remote access to the underlying host directly reduces exposure. Oracle has not published proof-of-concept code, and no public exploit is currently available.
Detection Methods for CVE-2026-62581
Indicators of Compromise
- Unexpected changes to Oracle Hyperion Infrastructure Technology configuration files or installation directories.
- New or modified privileged service accounts associated with the Hyperion installation on the host.
- Anomalous local logon sessions on servers hosting Oracle Hyperion Infrastructure Technology 11.2.25.0.000.
Detection Strategies
- Audit file integrity across Oracle Hyperion installation, configuration, and binary directories to detect unauthorized modifications.
- Correlate local interactive logons on Hyperion hosts with subsequent process execution against Hyperion binaries or configuration tooling.
- Alert on execution of configuration utilities by non-administrative accounts.
Monitoring Recommendations
- Enable and forward Windows Security and Linux auth logs from all Hyperion Infrastructure Technology hosts to a centralized logging platform.
- Monitor privilege changes, service creation, and scheduled task creation on Hyperion servers.
- Track process execution telemetry originating from Hyperion service accounts for deviations from baseline behavior.
How to Mitigate CVE-2026-62581
Immediate Actions Required
- Apply the fixes from the Oracle August 2026 Critical Patch Update to all affected Hyperion Infrastructure Technology deployments.
- Inventory hosts running Oracle Hyperion Infrastructure Technology 11.2.25.0.000 and prioritize patching for internet-adjacent or multi-tenant systems.
- Restrict interactive and remote logon rights on Hyperion hosts to a minimal set of administrative users.
Patch Information
Oracle addressed CVE-2026-62581 in the August 2026 Critical Patch Update. Administrators should review the Oracle Security Alert for version-specific patch identifiers and apply the vendor-supplied updates in a maintenance window.
Workarounds
- Enforce least privilege on all accounts with logon access to Hyperion Infrastructure Technology hosts until patches are applied.
- Segment Hyperion servers from general user workstations and restrict administrative access through jump hosts.
- Enable host-based auditing and file integrity monitoring on Hyperion installation directories to detect exploitation attempts.
# Configuration example: restrict interactive logon on Linux Hyperion hosts
# Limit SSH access to a dedicated admin group
sudo groupadd hyperion-admins
sudo usermod -aG hyperion-admins <admin_user>
echo 'AllowGroups hyperion-admins' | sudo tee -a /etc/ssh/sshd_config
sudo systemctl restart sshd
