CVE-2026-70972 Overview
CVE-2026-70972 is an access control vulnerability [CWE-284] affecting Oracle Hyperion Infrastructure Technology version 11.2.25.0.000. The flaw resides in the Installation and Configuration component. A low-privileged attacker with network access via HTTP can exploit the weakness, though successful exploitation requires meeting difficult preconditions.
Successful attacks allow unauthorized creation, deletion, or modification of critical data. Attackers can also gain unauthorized read access to all data accessible to Oracle Hyperion Infrastructure Technology. Oracle published the advisory as part of the August 2026 Critical Patch Update cycle.
Critical Impact
Authenticated attackers with low privileges can compromise the confidentiality and integrity of all data accessible through Oracle Hyperion Infrastructure Technology.
Affected Products
- Oracle Hyperion Infrastructure Technology 11.2.25.0.000
- Oracle Hyperion (Installation and Configuration component)
- Deployments exposing the Hyperion HTTP interface to authenticated users

Technical Details for CVE-2026-70972
Vulnerability Analysis
The vulnerability stems from improper access control [CWE-284] in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology. An authenticated attacker with low privileges can leverage network-accessible HTTP endpoints to bypass intended authorization boundaries. This grants access to data and operations that should be restricted to higher-privileged roles.
Exploitation is rated as difficult by Oracle. The attacker must satisfy specialized conditions beyond simply holding a valid low-privileged account. However, once exploited, the impact extends across the full scope of data accessible to the Hyperion Infrastructure Technology instance.
Availability is not affected. The vulnerability is scoped to confidentiality and integrity outcomes, meaning the service remains operational while an attacker reads, alters, or deletes protected records.
Root Cause
The root cause is a missing or improperly enforced authorization check within the Installation and Configuration component. The application does not correctly validate whether the calling user is entitled to perform sensitive administrative operations delivered over HTTP. This allows privilege boundaries to be crossed by any authenticated user.
Attack Vector
The attack vector is network-based. An attacker sends crafted HTTP requests to the Hyperion Infrastructure Technology service using a legitimate low-privileged account. No user interaction is required. Oracle has not published exploitation details, and no public proof-of-concept code is available. Refer to the Oracle Security Alert for vendor guidance.
Detection Methods for CVE-2026-70972
Indicators of Compromise
- Unexpected HTTP requests to Hyperion Installation and Configuration endpoints originating from low-privileged accounts
- Unauthorized creation, modification, or deletion events in Hyperion audit logs performed by non-administrative users
- Anomalous read access to configuration data or sensitive Hyperion datasets outside normal business workflows
Detection Strategies
- Enable and review Oracle Hyperion audit logging for administrative operations invoked by non-administrative principals
- Correlate web server access logs with application-level authorization events to identify privilege boundary violations
- Baseline expected HTTP traffic to the Installation and Configuration component and alert on deviations
Monitoring Recommendations
- Forward Hyperion application, audit, and web server logs to a centralized SIEM for retention and correlation
- Monitor authentication logs for low-privileged accounts exhibiting unusual access patterns against Hyperion services
- Alert on configuration or metadata changes performed outside sanctioned change management windows
How to Mitigate CVE-2026-70972
Immediate Actions Required
- Apply the Oracle Critical Patch Update referenced in the August 2026 Oracle Security Alert to affected Hyperion Infrastructure Technology deployments
- Inventory all Hyperion 11.2.25.0.000 instances and confirm patch status
- Restrict network reachability of Hyperion HTTP endpoints to trusted management networks
- Review and reduce standing privileges on Hyperion user accounts
Patch Information
Oracle addressed CVE-2026-70972 in the August 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert for the applicable patch identifiers and installation guidance for Oracle Hyperion Infrastructure Technology 11.2.25.0.000. Patching is the only vendor-supported remediation.
Workarounds
- Place Hyperion Infrastructure Technology behind a reverse proxy or web application firewall that restricts access to the Installation and Configuration endpoints
- Enforce network segmentation so only administrative subnets can reach the Hyperion HTTP interface
- Rotate credentials for low-privileged Hyperion accounts and audit role assignments to remove unnecessary access
