Frequently asked questions

What is Oracle Hyperion Data Relationship Management?

It is an enterprise software solution used by organizations for master data management. It helps companies maintain consistency across their information systems by providing a central hub to define, govern, and change core business data.

How does CVE-2026-70883 affect this software?

This vulnerability is an access control flaw within the system's security component. It means the software fails to properly verify the identity of someone trying to connect, allowing unauthorized parties to interact with or change sensitive information.

What triggers this vulnerability?

The flaw is triggered when an unauthorized user sends specific network requests over HTTP to the application. It does not require any prior login, account credentials, or special permissions to execute, making the system vulnerable to any network-based interaction.

Is my system at risk if it is not on the internet?

Halo Surface Signal indicates this software is typically an internal tool rather than a public-facing service. However, it remains reachable via internal networks, meaning any user or compromised device within your local network could potentially exploit it.

How should I respond to this threat?

Your first step is to locate every instance of this software within your infrastructure. Work with your platform and infrastructure teams to verify which systems are running version 11.2.25.0.000 and confirm who manages them so you can coordinate security updates.
