Frequently asked questions

What is Oracle Hyperion Data Relationship Management?

It is a master data management application used by organizations to maintain and govern critical business data. It helps enterprises ensure consistency across their financial and operational systems by centralizing the definitions and relationships of key data entities.

What is the vulnerability in CVE-2026-70872?

This CVE describes a weakness in the access and security component of the software. It allows an attacker to bypass authentication, meaning they do not need a username or password to interact with the system's core data management functions.

How does an attacker trigger this vulnerability?

An attacker triggers this by sending a specially crafted HTTP request over the network. The vulnerability does not require the attacker to have an existing user account, but it does require network connectivity to the affected component. Requests that do not reach the network-exposed security component will not trigger this issue.

Why should I care if my systems are not public-facing?

According to Halo Surface Signal, this software is typically found in internal corporate environments and is not designed to face the internet. While this limits broad visibility, anyone with access to your internal network could potentially reach the component, making it a risk for lateral movement within your organization.

What is the first step to address this CVE?

Start by identifying all instances of Oracle Hyperion Data Relationship Management within your infrastructure. Work with the application owners to confirm the current version, assess which instances are reachable over your network, and determine the business criticality of the data managed by those specific servers.
