CVE-2026-60393: Oracle Hyperion Information Disclosure

CVE-2026-60393 Overview

CVE-2026-60393 is a high-severity information disclosure vulnerability in Oracle Hyperion Infrastructure Technology, specifically within the Lifecycle Management component. The affected version is 11.2.25.0.000. An unauthenticated attacker with network access over HTTP can exploit this flaw to gain unauthorized access to critical data managed by Oracle Hyperion Infrastructure Technology. The vulnerability is classified under [CWE-200: Exposure of Sensitive Information to an Unauthorized Actor]. Oracle disclosed the issue as part of its August 2026 Critical Patch Update advisory.

Critical Impact
Unauthenticated remote attackers can extract sensitive data from Oracle Hyperion Infrastructure Technology deployments, resulting in complete confidentiality compromise of all accessible data.

Technical Details for CVE-2026-60393

Vulnerability Analysis

The vulnerability resides in the Lifecycle Management component of Oracle Hyperion Infrastructure Technology. Lifecycle Management (LCM) handles migration, backup, and artifact management across Hyperion services, meaning it processes and stores configuration data, application metadata, and user artifacts.

An attacker sends crafted HTTP requests to the affected component without authentication. The component fails to enforce proper access controls on sensitive resources, exposing data to unauthorized callers. Successful exploitation grants read access to critical data across the Hyperion environment.

Because Hyperion is commonly used for enterprise performance management, financial consolidation, and planning, the exposed data can include financial records, forecasting models, and business intelligence artifacts. The flaw does not affect integrity or availability, but confidentiality impact is complete.

Root Cause

The root cause is missing or improper authorization checks on HTTP endpoints served by the Lifecycle Management component [CWE-200]. Requests that should require authenticated session context are processed without validating caller identity or privileges.

Attack Vector

Attack complexity is low and no user interaction is required. An attacker with network reachability to the Hyperion HTTP interface sends specifically formed requests to Lifecycle Management endpoints. The service returns sensitive data without prompting for credentials. Refer to the Oracle Security Alert for vendor-supplied technical details.

No verified proof-of-concept code is publicly available at this time.

Detection Methods for CVE-2026-60393

Indicators of Compromise

Unauthenticated HTTP requests to Lifecycle Management endpoints originating from unexpected internal or external IP ranges.
Anomalous outbound data transfers from Hyperion application servers following inbound HTTP activity.
HTTP request patterns targeting /interop/, /lcm/, or related Hyperion Shared Services paths without preceding authentication events.

Detection Strategies

Inspect web server and reverse proxy logs for HTTP requests to Hyperion Lifecycle Management URIs that lack a valid session cookie or Authorization header.
Correlate high-volume artifact export or migration operations with authentication logs to identify sessionless activity.
Baseline normal Hyperion administrative traffic and alert on deviations, especially requests from non-administrative source IPs.

Monitoring Recommendations

Enable verbose access logging on Oracle HTTP Server and WebLogic instances fronting Hyperion services.
Forward Hyperion, WebLogic, and reverse proxy logs to a centralized log platform for correlation and long-term retention.
Configure alerting for repeated 200-status responses to Lifecycle Management endpoints without corresponding successful authentications.

How to Mitigate CVE-2026-60393

Immediate Actions Required

Apply the fixes provided in the Oracle August 2026 Critical Patch Update advisory to all Oracle Hyperion Infrastructure Technology 11.2.25.0.000 deployments.
Restrict network access to Hyperion HTTP interfaces to trusted administrative networks only, using firewalls or VPN gateways.
Audit recent Lifecycle Management activity for signs of unauthorized artifact export or configuration retrieval.

Patch Information

Oracle addressed CVE-2026-60393 in the August 2026 Critical Patch Update. Administrators should review the Oracle Security Alert and apply the referenced patch bundle for Oracle Hyperion Infrastructure Technology. Verify patch application by confirming the updated component version reported by the Hyperion Shared Services administrative console.

Workarounds

Place Oracle Hyperion HTTP endpoints behind a reverse proxy or web application firewall that enforces authentication before requests reach Lifecycle Management.
Disable or block external access to Lifecycle Management URIs when the component is not actively required for migrations.
Segment Hyperion servers into a restricted network zone with strict egress filtering to limit data exfiltration paths.

bash

# Example: restrict access to Hyperion Lifecycle Management via iptables
iptables -A INPUT -p tcp --dport 19000 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 19000 -j DROP
