CVE-2026-70882 Overview
CVE-2026-70882 is a vulnerability in the Access and security component of Oracle Hyperion Data Relationship Management (DRM). The flaw affects supported version 11.2.25.0.000 and is exploitable over the network via HTTP by a low-privileged attacker. Successful exploitation requires user interaction from a person other than the attacker. The vulnerability enables scope change, meaning attacks originating in DRM can impact additional Oracle Hyperion products. Impact covers unauthorized creation, deletion, or modification of critical data, and unauthorized read access to all DRM-accessible data.
Critical Impact
Authenticated attackers can trick users into actions that compromise the confidentiality and integrity of all Oracle Hyperion DRM data and extend impact to adjacent products.
Affected Products
- Oracle Hyperion Data Relationship Management 11.2.25.0.000
- Oracle Hyperion (Access and security component)
- Downstream Oracle Hyperion products reachable via scope change

Technical Details for CVE-2026-70882
Vulnerability Analysis
The vulnerability resides in the Access and security component of Oracle Hyperion Data Relationship Management. An authenticated attacker with low privileges can send crafted HTTP requests to the DRM application. Exploitation requires a separate user to interact with attacker-supplied content, consistent with client-side vectors such as reflected script execution or forged request flows. Once the victim interacts, the attacker gains unauthorized read, write, and delete access to DRM-managed data.
Because the vulnerable component performs a security scope change during exploitation, the impact extends beyond DRM itself. Attackers can pivot the compromise to other Oracle Hyperion products that trust the DRM security boundary. Oracle rates the confidentiality and integrity impact as high, with no direct availability impact.
Root Cause
Oracle has not published root cause details in the referenced advisory. The CVSS profile — low privileges required, user interaction required, and scope change — is characteristic of a web-layer access control or injection defect in an authenticated session context. Refer to the Oracle Security Alert for vendor-authoritative details.
Attack Vector
The attack vector is network-based over HTTP. An attacker with a low-privileged DRM account crafts a malicious request or link and induces a legitimate user to execute the action within an authenticated session. The victim's privileges are leveraged to perform unauthorized data operations across DRM and adjacent Hyperion products via the resulting scope change.
No verified exploit code is publicly available for CVE-2026-70882. See the vendor advisory for guidance.
Detection Methods for CVE-2026-70882
Indicators of Compromise
- Unexpected creation, modification, or deletion of DRM hierarchies, nodes, properties, or versions performed by low-privileged accounts.
- HTTP requests to DRM endpoints originating from unusual referrers or containing crafted parameters targeting the Access and security component.
- Authentication or authorization events showing privilege usage inconsistent with a user's normal role in DRM.
Detection Strategies
- Correlate DRM audit logs with web server access logs to identify user-interaction driven actions that deviate from baseline workflows.
- Alert on cross-product access events where a DRM session initiates operations against other Oracle Hyperion services in short succession.
- Baseline normal DRM API and UI usage per role, then flag deviations such as bulk deletions or mass property modifications by non-administrative users.
Monitoring Recommendations
- Forward Oracle Hyperion DRM application, audit, and web-tier logs to a centralized analytics platform for continuous review.
- Monitor outbound links and email delivered to DRM users for suspicious URLs that reference the DRM host, given the required user-interaction vector.
- Review privileged operation reports weekly until patches are applied and validated in production.
How to Mitigate CVE-2026-70882
Immediate Actions Required
- Apply the fixes documented in the Oracle Security Alert for Oracle Hyperion Data Relationship Management 11.2.25.0.000.
- Restrict network access to the DRM web tier to trusted corporate networks and VPN users only.
- Review and reduce DRM account privileges; remove dormant accounts and enforce least privilege for standard users.
- Communicate phishing and link-handling guidance to DRM users, since exploitation requires victim interaction.
Patch Information
Oracle addresses this vulnerability in its Critical Patch Update cycle. Administrators should install the patch referenced in the Oracle Security Alert for August 2026 and validate that the DRM 11.2.25.0.000 deployment reports the updated build number after installation.
Workarounds
- Place DRM behind a web application firewall configured to inspect and filter unexpected request patterns to the Access and security component.
- Enforce strict SameSite cookie policies and modern browser controls for DRM sessions to reduce client-side abuse.
- Segment Oracle Hyperion products at the network layer to limit the reach of scope-change impact until the patch is deployed.
# Configuration example: restrict DRM web tier access at the network layer
# Replace CIDR ranges with your trusted management and user subnets
iptables -A INPUT -p tcp --dport 443 -s 10.10.0.0/16 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
