CVE-2026-70736 Overview
CVE-2026-70736 affects the Deployment component of Oracle Hyperion Profitability and Cost Management. The vulnerability impacts supported version 11.2.25.0.000. A low-privileged attacker with network access via HTTP can exploit this flaw to compromise the application. Successful exploitation grants unauthorized access to critical data or complete access to all data accessible by the product. Attackers can also perform unauthorized update, insert, or delete operations against a subset of accessible data.
Critical Impact
A remote authenticated attacker holding only low privileges can read all application data and modify a subset, breaking confidentiality and integrity of financial planning data.
Affected Products
- Oracle Hyperion Profitability and Cost Management 11.2.25.0.000
- Oracle Hyperion product family (Deployment component)
- Enterprise Performance Management (EPM) environments running the affected release

Technical Details for CVE-2026-70736
Vulnerability Analysis
The flaw resides in the Deployment component of Oracle Hyperion Profitability and Cost Management. An authenticated attacker sends crafted HTTP requests over the network to reach vulnerable deployment functionality. The vulnerability produces high confidentiality impact and low integrity impact, with no availability effect. Because the attack executes remotely and requires only low-tier account privileges, exposed Hyperion instances present a realistic target for lateral movement inside financial and planning environments. The EPSS score of 0.303% reflects a current low probability of observed exploitation, but the ease of exploitation raises long-term risk.
Root Cause
Oracle has not published a detailed technical breakdown of the underlying defect. Based on the CVSS metrics and the affected component, the issue stems from insufficient authorization enforcement inside deployment workflows. The Deployment component appears to expose functionality that trusts a low-privileged session for actions that should require administrative context. This allows the caller to read protected data and mutate records outside the intended role boundary.
Attack Vector
The attacker authenticates with any low-privileged Hyperion account, then issues HTTP requests to deployment endpoints. No user interaction is required, and the attack does not cross a security boundary that would change scope. The vulnerability manifests through the standard web tier used by Hyperion Profitability and Cost Management deployments. Refer to the Oracle Security Alert for vendor-supplied technical context.
Detection Methods for CVE-2026-70736
Indicators of Compromise
- Unexpected HTTP requests to Hyperion Profitability and Cost Management deployment endpoints originating from non-administrative user sessions.
- Bulk read access to profitability model data by user accounts that historically only consume reports.
- Unauthorized INSERT, UPDATE, or DELETE operations recorded in Hyperion application audit logs.
- Session activity from low-privileged accounts that includes deployment or configuration API calls.
Detection Strategies
- Enable and centralize Hyperion application, web tier, and database audit logs, then baseline normal deployment activity per role.
- Alert on any deployment-component access performed by accounts not assigned an administrator role.
- Correlate authentication events with subsequent access to Profitability and Cost Management data objects to surface privilege anomalies.
Monitoring Recommendations
- Forward Hyperion web server, WebLogic, and database logs to a SIEM for retention and cross-source correlation.
- Track HTTP request volume and error rates on deployment URIs to catch enumeration attempts.
- Review privileged data changes daily until the patch is confirmed applied across all nodes.
How to Mitigate CVE-2026-70736
Immediate Actions Required
- Apply the fixes distributed in the Oracle Critical Patch Update referenced in the Oracle Security Alert.
- Inventory all Oracle Hyperion Profitability and Cost Management instances and confirm the running version against 11.2.25.0.000.
- Rotate credentials for low-privileged Hyperion accounts and review recent activity from those accounts.
Patch Information
Oracle addresses CVE-2026-70736 in the August 2026 Critical Patch Update for Oracle Hyperion. Administrators should download and deploy the patch identified in the vendor advisory, then restart affected services. Validate the patch level in the Hyperion administration console after installation to confirm remediation.
Workarounds
- Restrict network access to Hyperion web interfaces so that only trusted management networks can reach deployment endpoints.
- Enforce least privilege on Hyperion roles and remove unused low-privileged accounts pending patch deployment.
- Place a web application firewall or reverse proxy in front of Hyperion to filter unexpected deployment-component requests.
- Increase audit logging verbosity on the Deployment component until the patch is verified in production.
