MITRE ATT&CK
1 technique across 1 tactic: Defense Evasion The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | The only prerequisite is network HTTP access to an Oracle Hyperion DRM 11.2.25.0.000 instance's web interface; per the CVSS vector AV:N/AC:L/PR:N/UI:N there is no authentication, no user interaction, and no special non-default configuration required, and the 'Authentication Bypass' tag confirms credentials are not needed. The primary limiting factor is reachability: exploitation requires that the attacker can route HTTP to the DRM front end, so deployments that keep DRM on an isolated internal segment or behind a VPN/allowlist substantially reduce exposure. The affected scope is confined to the named 11.2.25.0.000 build in the source data, so environments on other versions should confirm applicability against Oracle's advisory. |
| Impact | The signals converge on genuine priority: the CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N is fully unauthenticated, network-reachable, low-complexity, and needs no user interaction, and Oracle self-rates it 9.1 with High confidentiality and integrity impact. The 'Authentication Bypass' tag reinforces that the barrier to exploitation is effectively an exposed HTTP endpoint. Tempering that, there is no EPSS score in the provided data, no POC, and no CISA KEV listing, so widespread automated exploitation is not yet evidenced - this reads as high inherent exploitability without confirmed in-the-wild activity. Any organization that exposes DRM's web interface, even a mid-sized operator running a single production instance, should treat this as urgent and patch on Oracle's Critical Patch Update cycle rather than waiting for exploitation reports. The absence of Availability impact (A:N) means this is a data-confidentiality/integrity risk, not a denial-of-service one, which should shape but not lower prioritization. |
| Exploit ScenarioDerived | An attacker who can reach the Hyperion DRM web interface - for example an internal user, or an external actor if the interface is internet-exposed - sends crafted HTTP requests that bypass authentication in the Access and security component. With no credentials and no user interaction, they read sensitive master-data hierarchies and then create, alter, or delete governance records, corrupting data that feeds downstream financial systems. No public POC is currently identified, but the low complexity means a working exploit could be developed quickly once details circulate. |

Alert meAnalysisAIv1 – Aug 19, 2026
Unauthenticated remote compromise of Oracle Hyperion Data Relationship Management 11.2.25.0.000 (Access and security component) allows network attackers to read, create, modify, or delete all data accessible to the application over HTTP without any credentials. Oracle rates it CVSS 3.1 9.1 and tags it as an authentication bypass, meaning an attacker who can reach the web interface gains full confidentiality and integrity impact over master-data governance records. No public exploit identified at time of analysis and it is not listed in CISA KEV, but the low attack complexity and lack of authentication make it a high-priority patch.
RemediationAI
Apply the fix from Oracle's August 2026 Critical Patch Update as documented at https://www.oracle.com/security-alerts/cspuaug2026.html; the input does not contain an exact patched build number, so the specific fixed version should be taken directly from that advisory rather than assumed (patch available per vendor advisory, released patched version not independently confirmed here). Until patched, restrict network reachability of the DRM HTTP interface: place it behind a VPN or IP-allowlist so only trusted administrative networks can reach it, and remove any direct internet exposure - the trade-off is reduced remote-admin convenience but this directly negates the AV:N precondition. Additionally, front the application with a reverse proxy or WAF enforcing authentication at the edge and monitor DRM access logs for anomalous unauthenticated data-access requests; note that edge auth is a compensating control, not a substitute for the vendor patch, since it does not fix the underlying bypass.

Technical ContextAI · show details
Oracle Hyperion Data Relationship Management (DRM) is an enterprise master-data management application within Oracle's Enterprise Performance Management (EPM) suite, used to govern hierarchies, reference data, and chart-of-accounts structures shared across financial and analytics systems. The flaw sits in the 'Access and security' component and is tagged as an authentication bypass, indicating a defect in how the HTTP front end validates or enforces user identity/session state rather than a memory-safety bug. Oracle did not assign a CWE (CWE: N/A), but the behavior is consistent with the CWE-287/CWE-306 class (improper or missing authentication) given that an unauthenticated request reaches privileged data operations. Because DRM sits upstream of downstream reporting and consolidation systems, integrity impact here can propagate into dependent financial data flows.

DescriptionCVE.org
Vulnerability in the Oracle Hyperion Data Relationship Management product of Oracle Hyperion (component: Access and security). The supported version that is affected is 11.2.25.0.000. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Hyperion Data Relationship Management. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Data Relationship Management accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Data Relationship Management accessible data. CVSS 3.1 Base Score 9.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).
Executive ViewAI
Oracle Hyperion Data Relationship Management 11.2.25.0.000 contains a critical authentication bypass enabling unauthenticated network attackers to read, modify, or delete all enterprise master data governance records. Organizations using this product face immediate risk of complete data theft or corruption, with no vendor patch currently available. Urgent network isolation and access restrictions are required to prevent unauthorized compromise of business-critical reference data.
No vendor-released patch identified at time of analysis. Interim mitigations: restrict network access via firewall to internal networks and trusted administrators only, disable HTTP interface access and enforce HTTPS with certificate-based authentication where available, implement application-level access controls and comprehensive audit logging for all data access, segment the application network from sensitive data repositories, and monitor authentication attempts for unauthorized access patterns.
