Frequently asked questions

What is Oracle Commerce Experience Manager?

It is a specialized software component within the Oracle Commerce suite that powers guided search and content management for e-commerce websites. Businesses use it to help customers find products, manage search relevance, and deliver personalized shopping experiences through web-based interfaces.

How does CVE-2026-70997 affect the system?

This vulnerability allows an attacker to interact with the software without needing a login. It functions as a security weakness that can be manipulated to steal sensitive information stored in the system or to overwhelm the application, causing it to crash and become unavailable to legitimate users.

Do I need special access to trigger this vulnerability?

No. The vulnerability is triggered by sending a specially crafted HTTP request over a network. Since the software does not require authentication to receive and process these requests, an attacker does not need any privileged access, internal accounts, or prior permission to interact with the affected component.

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

Halo Surface Signal indicates that because this software is typically designed as a web-based storefront interface, it is often exposed to the public internet. If your specific instance is hosted internally and restricted from public network access, the likelihood of an external actor reaching it is reduced, though internal network security remains a factor.

How should I respond to this threat advisory?

Start by identifying all servers running Oracle Commerce Guided Search or Experience Manager version 11.4.0 in your environment. Once found, coordinate with your application and platform owners to evaluate the business impact of these systems and develop a plan to address the vulnerability, such as applying vendor-provided security updates.
