Oracle Hyperion Data Relationship Management Access and Security Vulnerability Allows Takeover

CVE advisorySeverity: CRITICAL (CVSS 10.0)

CVE-2026-70880

Oracle Hyperion Data Relationship Management is typically deployed within internal corporate networks to manage master data. While it utilizes TCP network access, it is generally not designed to be exposed directly to the public internet, usually sitting behind internal firewalls or identity controls in enterprise environments.

Halo Surface Signal: 2 out of 5 — less likely to be public-facing.

Frequently asked questions

What is Oracle Hyperion Data Relationship Management?

It is a specialized enterprise application used to manage master data, helping organizations maintain consistency across their financial and operational systems by controlling how data relationships and hierarchies are structured.

How does CVE-2026-70880 affect software security?

This vulnerability indicates a flaw in the product's Access and Security component. It allows an attacker to bypass authentication entirely, granting them unauthorized control over the software and potentially impacting other connected systems.

Do I need to be logged in to trigger CVE-2026-70880?

No. The vulnerability is triggered by an unauthenticated attacker sending a specially crafted request over a TCP network connection. It does not require a legitimate user session to initiate the exploit.

Is my system at risk if it is not internet-facing?

Halo Surface Signal notes that while this software is typically kept behind firewalls on internal networks, any system with TCP network access—internal or otherwise—is technically capable of being reached by an attacker who has gained a foothold on your network.

What steps should I take if I use Hyperion Data Relationship Management?

Begin by identifying all running instances of version 11.2.25.0.000 in your environment. Evaluate their business function and network placement, then coordinate with your internal security and vendor teams to plan and apply the necessary patches.
