CVE-2026-62467 Overview
CVE-2026-62467 is a high-severity vulnerability in the Oracle Hyperion Infrastructure Technology product, specifically within the Common Events component. The affected version is 11.2.25.0.000. An attacker with low privileges and network access via HTTP can exploit this weakness to gain unauthorized access to sensitive Hyperion data. The vulnerability introduces a scope change, meaning successful exploitation can impact resources beyond the vulnerable component itself. Oracle disclosed the issue in its August 2026 Critical Patch Update.
Critical Impact
Successful exploitation grants unauthorized access to critical data or complete read access to all Oracle Hyperion Infrastructure Technology accessible data, with cross-component impact due to scope change.
Affected Products
- Oracle Hyperion Infrastructure Technology 11.2.25.0.000
- Oracle Hyperion (Common Events component)
- Deployments exposing Hyperion HTTP endpoints to networked users

Technical Details for CVE-2026-62467
Vulnerability Analysis
The flaw resides in the Common Events component of Oracle Hyperion Infrastructure Technology. It is classified as an information disclosure vulnerability with confidentiality-only impact. An authenticated attacker holding low-level privileges can send crafted HTTP requests to the Hyperion service. The vulnerability is easily exploitable and does not require user interaction. Because the CVSS vector indicates a scope change, exploitation can affect data managed by adjacent Hyperion products, not just the Common Events component.
Root Cause
Oracle has not published detailed root cause information. Based on the advisory metadata, the weakness enables a low-privileged authenticated user to reach data they should not be authorized to view. This pattern is consistent with broken access control or missing authorization checks in the Common Events handling logic. Refer to the Oracle Security Alert for vendor-authoritative details.
Attack Vector
The attack originates from the network over HTTP. An attacker authenticates with any low-privileged Hyperion account, then issues requests to Common Events endpoints. Attack complexity is low, and no user interaction is required. The result is unauthorized read access to critical Hyperion data. Integrity and availability are not directly impacted by this CVE, but disclosed data may enable follow-on attacks.
No public proof-of-concept code has been observed for CVE-2026-62467 at the time of writing. See the Oracle Security Alert for technical remediation guidance.
Detection Methods for CVE-2026-62467
Indicators of Compromise
- Unusual HTTP requests from low-privileged accounts targeting Hyperion Common Events endpoints.
- Elevated volumes of successful reads against Hyperion data resources not typically accessed by the source account.
- Authentication events from service or reporting accounts followed by anomalous data retrieval activity.
Detection Strategies
- Baseline expected access patterns for the Common Events component and alert on deviations by user, source IP, and endpoint.
- Correlate HTTP access logs with identity data to flag low-privileged sessions retrieving high-sensitivity records.
- Review Hyperion audit logs for cross-component data access consistent with a scope-change exploitation path.
Monitoring Recommendations
- Forward Hyperion application, HTTP server, and authentication logs to a centralized analytics platform for correlation.
- Monitor egress traffic from Hyperion hosts for bulk data transfers following suspicious HTTP request bursts.
- Track privileged and low-privileged account behavior against Hyperion endpoints and alert on unexpected role-to-resource pairings.
How to Mitigate CVE-2026-62467
Immediate Actions Required
- Apply the fixes documented in the Oracle August 2026 Critical Patch Update as soon as change windows allow.
- Inventory all Hyperion Infrastructure Technology 11.2.25.0.000 deployments and prioritize internet-exposed or business-critical instances.
- Audit and reduce the number of low-privileged accounts with HTTP access to Hyperion services.
Patch Information
Oracle addressed CVE-2026-62467 in the August 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert for the applicable patch bundle, prerequisites, and installation guidance for Oracle Hyperion Infrastructure Technology 11.2.25.0.000.
Workarounds
- Restrict network access to Hyperion HTTP endpoints using firewalls, reverse proxies, or VPN gating until patches are applied.
- Enforce least privilege on Hyperion accounts and remove unused or dormant low-privilege users.
- Enable enhanced HTTP request logging and audit logging on Hyperion to preserve forensic evidence during the patch window.
# Example: restrict Hyperion HTTP access to trusted management subnet
# Replace 10.10.20.0/24 with your trusted network and adjust interface as needed
iptables -A INPUT -p tcp --dport 19000 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 19000 -j DROP
