Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability has been identified in Oracle WebCenter Content, a platform used for managing digital content within organizations. This issue could allow unauthorized access to modify or delete critical data, or gain complete access to all content. The vulnerability is exploitable over a network and requires some user interaction to be successful, potentially impacting other connected products.

  • An attacker could alter or steal important content.
  • It affects a key enterprise content management system.
  • Confirm if this content system is in use.

Attack Path

How an attacker could exploit the issue

An attacker can exploit this vulnerability by sending a crafted request over the network to an exposed Oracle WebCenter Content server. This attack requires the user to interact with a malicious link or file, which then triggers the vulnerability within the Content Server component. Successful exploitation allows an attacker to gain unauthorized control over critical data, potentially leading to data modification or deletion.

  • Network access required.
  • User interaction to trigger.
  • Unauthorized data access and modification.

Live Threat

Frequently asked questions

What is Oracle WebCenter Content?

Oracle WebCenter Content is a component of Oracle Fusion Middleware designed for enterprise content management. It serves as a centralized repository where organizations store, organize, and manage digital documents, web assets, and business records to support collaborative workflows.

How should I interpret the weakness identified in CVE-2026-46805?

This vulnerability is classified under CWE-284, which deals with improper access control. In plain terms, it means the system fails to properly verify if a user has the right to perform specific actions, allowing an unauthorized person to potentially read, modify, or delete sensitive data that should be protected.

Does this vulnerability trigger automatically when a server is reached?

No. While the vulnerability is reachable over a network via HTTP, it does not execute automatically. A successful attack requires human interaction; specifically, a user must be persuaded to interact with a malicious link or file, which then triggers the vulnerability in the Content Server component.

How do I know if my systems are at risk according to Halo Surface Signal?

Halo Surface Signal identifies this as a 'Likely' risk because Oracle WebCenter Content is typically deployed as a web application. Whether accessed over the internet or restricted to an internal intranet, if the service is reachable via standard HTTP web patterns, it meets the network access requirement for this vulnerability.

What is the first step to address this issue?

Your priority is to identify all instances of version 14.1.2.0.0 within your environment. Once located, verify the criticality of the data hosted on those servers and coordinate with your technical teams to plan remediation, ensuring that responsible owners are aware of the potential for unauthorized data access.
