CVE-2026-62551 Overview
CVE-2026-62551 is a vulnerability in the Oracle Hyperion Infrastructure Technology product of Oracle Hyperion, specifically in the Installation and Configuration component. The affected supported version is 11.2.25.0.000. An unauthenticated attacker with network access via HTTP can exploit this weakness to compromise Oracle Hyperion Infrastructure Technology. Successful exploitation allows unauthorized update, insert, or delete access to a subset of accessible data, unauthorized read access to a subset of accessible data, and a partial denial of service. The weakness maps to [CWE-284: Improper Access Control].
Critical Impact
Unauthenticated network attackers can modify or read a subset of Oracle Hyperion data and cause partial service disruption without user interaction.
Affected Products
- Oracle Hyperion Infrastructure Technology 11.2.25.0.000
- Component: Installation and Configuration
- Oracle Hyperion product family

Technical Details for CVE-2026-62551
Vulnerability Analysis
The vulnerability affects the Installation and Configuration component of Oracle Hyperion Infrastructure Technology. An attacker reaches the vulnerable functionality over HTTP without authenticating and without user interaction. Successful exploitation grants limited write access to Hyperion accessible data, limited read access to a subset of that data, and the ability to cause a partial denial of service.
Oracle classifies the flaw as easily exploitable. The scope is unchanged, meaning the compromise remains within the Hyperion component boundary. The confidentiality, integrity, and availability impacts are each rated Low, reflecting that only a subset of data and functionality is at risk rather than the entire application.
Root Cause
The underlying weakness is Improper Access Control [CWE-284]. Installation and Configuration endpoints exposed by Hyperion Infrastructure Technology fail to enforce sufficient authorization checks. As a result, requests that should require authenticated administrative context can be issued directly by remote clients.
Attack Vector
An attacker sends crafted HTTP requests to a network-reachable Oracle Hyperion Infrastructure Technology deployment running the affected version. Because privileges and user interaction are not required, exposure of the management or configuration interface to untrusted networks materially increases risk. Oracle has not published exploitation code, and no public proof-of-concept is available at this time.
Technical specifics beyond Oracle's advisory summary have not been released. Refer to the Oracle Security Alert August 2026 for vendor-authoritative details.
Detection Methods for CVE-2026-62551
Indicators of Compromise
- Unauthenticated HTTP requests to Hyperion Installation and Configuration endpoints originating from unexpected source addresses
- Unexpected creation, modification, or deletion of configuration records within Hyperion Infrastructure Technology
- Abnormal HTTP error rates or service restarts consistent with a partial denial-of-service condition
Detection Strategies
- Inventory Hyperion Infrastructure Technology deployments and confirm which run version 11.2.25.0.000
- Enable verbose access logging on Hyperion web tiers and forward logs to a centralized analytics platform for correlation
- Alert on HTTP requests to configuration or installation URLs that lack a valid authenticated session
Monitoring Recommendations
- Monitor egress and ingress traffic to Hyperion management interfaces for anomalous request patterns
- Track configuration drift on Hyperion nodes using file integrity monitoring and change auditing
- Review authentication logs for gaps that coincide with configuration changes
How to Mitigate CVE-2026-62551
Immediate Actions Required
- Apply the fixes referenced in the Oracle Security Alert August 2026 to all affected Hyperion Infrastructure Technology instances
- Restrict network access to Hyperion administrative and configuration endpoints to trusted management networks only
- Audit recent Hyperion configuration and data changes for unauthorized activity
Patch Information
Oracle addressed this vulnerability in the Oracle Security Alert Advisory published August 2026. Administrators should review the advisory and apply the vendor-provided update for Oracle Hyperion Infrastructure Technology 11.2.25.0.000. See the Oracle Security Alert August 2026 for the complete patch matrix.
Workarounds
- Place Hyperion Infrastructure Technology behind a reverse proxy or web application firewall that enforces authentication before requests reach the application
- Block external access to Installation and Configuration URIs at the network perimeter
- Segment Hyperion servers from general user networks and require VPN or bastion access for administration
