CVE-2026-60391 Overview
CVE-2026-60391 is a high-severity vulnerability in the Oracle Hyperion Financial Reporting product, a component of the Oracle Hyperion platform. The flaw resides in the Server component and affects supported version 11.2.25.0.000. An unauthenticated attacker with network access via HTTP can exploit this weakness to compromise Oracle Hyperion Financial Reporting. Successful exploitation results in unauthorized read access to all data accessible through the application. The Common Weakness Enumeration classifies this issue under improper access control [CWE-284].
Critical Impact
Remote, unauthenticated attackers can obtain complete access to sensitive financial reporting data over the network, exposing confidential enterprise financial information.
Affected Products
- Oracle Hyperion Financial Reporting
- Oracle Hyperion Financial Reporting Server component
- Oracle Hyperion Financial Reporting version 11.2.25.0.000

Technical Details for CVE-2026-60391
Vulnerability Analysis
The vulnerability affects the Server component of Oracle Hyperion Financial Reporting. Oracle categorizes the flaw as easily exploitable, meaning an attacker requires no authentication, no user interaction, and no elevated privileges. The attack occurs across the network over HTTP, making it accessible to any adversary who can reach the reporting server. Exploitation grants read access to critical business data managed by the application.
The Exploit Prediction Scoring System (EPSS) currently rates this vulnerability at 0.377%, placing it in the 31st percentile for exploitation likelihood in the wild. No public proof-of-concept exploits have been observed at the time of publication.
Root Cause
The underlying weakness maps to [CWE-284] Improper Access Control. The Server component fails to enforce sufficient authorization checks on HTTP-accessible functionality. As a result, requests that should require authenticated sessions with proper role validation are processed without restriction, exposing data that should be protected.
Attack Vector
An attacker sends crafted HTTP requests directly to the Oracle Hyperion Financial Reporting Server. Because no credentials or session tokens are required, exploitation can be automated against any exposed instance. The impact is limited to confidentiality; integrity and availability of the system are not directly affected. Organizations that expose Hyperion Financial Reporting to untrusted networks face the highest risk.
No verified public exploit code is available. See the Oracle Security Alert for authoritative technical details.
Detection Methods for CVE-2026-60391
Indicators of Compromise
- Unauthenticated HTTP requests to Oracle Hyperion Financial Reporting Server endpoints originating from unexpected source addresses.
- Anomalous volumes of report retrieval or data export activity outside normal business hours.
- Web server access logs showing successful HTTP 200 responses on sensitive endpoints without an associated authenticated session identifier.
Detection Strategies
- Review Hyperion application and web server logs for repeated access attempts to reporting endpoints without preceding authentication events.
- Correlate outbound data transfer volumes from Hyperion servers against historical baselines to identify bulk exfiltration.
- Deploy web application firewall (WAF) rules that flag requests to Hyperion Financial Reporting paths lacking valid session cookies.
Monitoring Recommendations
- Enable verbose HTTP request logging on Oracle Hyperion Financial Reporting Server and forward logs to a centralized SIEM.
- Monitor network flow data for connections to Hyperion servers from network segments that should not have access.
- Establish alerting on repeated 4xx-to-2xx status transitions that may indicate authorization bypass probing.
How to Mitigate CVE-2026-60391
Immediate Actions Required
- Apply the Oracle Critical Patch Update referenced in the Oracle Security Alert to all Oracle Hyperion Financial Reporting 11.2.25.0.000 deployments.
- Restrict network access to Hyperion Financial Reporting Server to trusted internal segments and VPN users only.
- Audit recent HTTP access logs for signs of unauthorized data retrieval prior to patching.
Patch Information
Oracle addressed CVE-2026-60391 in the August 2026 Critical Patch Update. Administrators should download and apply the fix documented in the Oracle Security Alert. Verify the patch level after installation and restart affected Hyperion services to activate the corrected access control checks.
Workarounds
- Place Oracle Hyperion Financial Reporting behind a reverse proxy or WAF that enforces authentication before requests reach the server.
- Block internet-facing exposure of Hyperion Financial Reporting through firewall rules and remove any public DNS records pointing to the application.
- Enforce network-layer access control lists (ACLs) that restrict HTTP traffic to Hyperion servers to authorized administrative subnets until patching is complete.
