Oracle Universal Work Queue Takeover Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.9)

CVE-2026-46824

The vulnerability affects Oracle E-Business Suite, an enterprise resource planning application. While the component is accessible via HTTP, such systems are typically deployed within internal networks and not intended for direct public exposure. Accessibility varies significantly based on specific network configurations and remote access policies implemented by the organization.

Operational Fix

Recommended remediation, mitigation, and detection steps

The Oracle Universal Work Queue within Oracle E-Business Suite, specifically affecting versions 12.2.3 through 12.2.15, presents a critical risk due to its exploitable nature via HTTP by low-privileged attackers. This vulnerability can lead to a complete takeover of the Universal Work Queue and potentially impact other connected products. Ownership likely falls to the E-Business Suite application administrators, supported by infrastructure and security teams. The immediate first step is to identify all instances of the affected Oracle Universal Work Queue, confirm their network exposure and business criticality, and then prioritize remediation based on these findings.

Application owners should lead remediation efforts.
Verify network exposure and criticality.
Plan remediation based on risk assessment.

Frequently asked questions

What is Oracle Universal Work Queue?

It is a component of Oracle E-Business Suite that helps organizations manage and route work items—like tasks or service requests—to the appropriate staff. It acts as a central hub for task distribution within the larger enterprise resource planning (ERP) platform, ensuring that data and service workflows are organized for users across the system.

What does CVE-2026-46824 mean?

This CVE represents a security flaw where the system fails to properly control access or verify identity, categorized under weaknesses like improper privilege management and authentication issues. In plain terms, it allows an unauthorized user to bypass intended restrictions and gain full control over the Work Queue, effectively overriding the normal security boundaries that should prevent such deep system access.

How is this vulnerability triggered?

An attacker triggers this by sending specially crafted HTTP requests to the Work Provider Site Level Administration feature. Importantly, the vulnerability does not trigger if the attacker lacks network access to this interface or does not possess the required low-level user credentials. It requires a combination of network connectivity and the ability to interact with this specific administrative component to succeed.

Do I need to worry if my system is internal?

Yes, but your risk depends on your network setup. While Halo Surface Signal notes this system is often kept on internal networks rather than being publicly exposed, internal access still poses a risk. If your network configuration or remote access policies allow users—or compromised internal accounts—to reach the HTTP interface, the system remains vulnerable to potential exploitation.

When should I address this?

You should prioritize this immediately by identifying all instances of the affected Oracle E-Business Suite versions in your environment. Since this flaw can lead to a complete system takeover and impact connected products, collaborate with your application and infrastructure teams to confirm the software versions, assess your specific network exposure, and plan your update or remediation strategy promptly.
