CVE-2026-70875 Overview
CVE-2026-70875 affects the Oracle Hyperion Data Relationship Management product within the Oracle Hyperion suite. The vulnerability resides in the Access and security component of version 11.2.25.0.000. A low-privileged attacker with network access via HTTP can compromise the application, though exploitation is difficult. Successful exploitation results in full takeover of Oracle Hyperion Data Relationship Management, impacting confidentiality, integrity, and availability. Oracle disclosed the issue in the Oracle Security Alert August 2026.
Critical Impact

Technical Details for CVE-2026-70875
Vulnerability Analysis
The flaw resides in the Access and security component of Oracle Hyperion Data Relationship Management (DRM). DRM manages master data hierarchies and governance policies across Oracle Hyperion financial and enterprise performance management deployments. A weakness in how the component enforces access and security controls allows an authenticated attacker to escalate their effective privileges within the application.
Exploitation is rated as difficult, which typically indicates that specific runtime conditions, timing, or configuration states must align for the attack to succeed. Once those conditions are met, the attacker can compromise the entire application, extract sensitive master data, alter hierarchies, or disrupt service.
Oracle has not published the underlying CWE classification for this issue. The Oracle Security Alert entry categorizes the impact as a full takeover, meaning the attacker inherits control over data, application logic, and availability.
Root Cause
Oracle's advisory attributes the issue to the Access and security component without disclosing implementation details. The condition permits a user holding low privileges to reach functionality or data that should require higher authorization, resulting in broken access control within the DRM application layer.
Attack Vector
The attack originates over the network via HTTP against the DRM web interface. The attacker must already hold low-privileged credentials to the application. No user interaction is required, and the scope remains unchanged, but exploitation complexity is high. The EPSS score is 0.27% at the 19.273 percentile as of 2026-08-23, indicating a low near-term probability of observed exploitation.
No public proof-of-concept or exploit code is available. For technical scope, refer to the Oracle Security Alert August 2026.
Detection Methods for CVE-2026-70875
Indicators of Compromise
- Unexpected privilege changes, role assignments, or hierarchy modifications performed by low-privileged DRM accounts.
- Anomalous HTTP requests to DRM administrative endpoints originating from non-administrative user sessions.
- Unusual export, batch, or metadata operations outside documented change windows.
Detection Strategies
- Review DRM audit logs for access control decisions where low-privileged users successfully invoked restricted operations.
- Correlate web server access logs with application audit trails to identify HTTP requests that bypass expected role enforcement.
- Baseline normal user behavior in DRM and alert on deviations such as sudden increases in privileged actions per session.
Monitoring Recommendations
- Forward DRM application logs, IIS or web tier logs, and database audit events to a centralized analytics platform for correlation.
- Monitor authentication events for reused credentials or session anomalies against DRM endpoints.
- Track configuration changes to DRM security groups, node access, and property definitions with alerting on out-of-policy edits.
How to Mitigate CVE-2026-70875
Immediate Actions Required
- Apply the fixes referenced in the Oracle Security Alert August 2026 to Oracle Hyperion Data Relationship Management 11.2.25.0.000.
- Inventory all Hyperion DRM instances and confirm patch status for each environment, including non-production tiers.
- Rotate credentials for DRM application accounts and review role assignments for least privilege.
Patch Information
Oracle has released fixes as part of the August 2026 Critical Patch Update cycle. Administrators should follow the guidance in the Oracle Security Alert August 2026 and apply the vendor-supplied patch to affected DRM installations. Confirm patch application by validating the DRM build version after deployment.
Workarounds
- Restrict HTTP access to the DRM web tier using network segmentation, VPN, or reverse proxy allowlists until patches are applied.
- Reduce the number of low-privileged DRM accounts and disable inactive users to shrink the attack surface.
- Enforce multifactor authentication on identity providers that federate into Hyperion to raise the cost of credential abuse.
# Configuration example: restrict DRM web tier access at the firewall
# Replace <trusted_subnet> and <drm_host> with environment values
iptables -A INPUT -p tcp --dport 443 -s <trusted_subnet> -d <drm_host> -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -d <drm_host> -j DROP
