Oracle Hyperion Infrastructure Technology Common Events Takeover Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-62457

The vulnerability affects the Common Events component of Oracle Hyperion, a suite typically deployed in internal enterprise environments. While it is accessible via network HTTP, these systems are generally positioned behind internal controls or VPNs rather than being directly exposed to the public internet as a standard deployment pattern.

Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability has been identified in Oracle Hyperion Infrastructure Technology, specifically within the Common Events component. This issue is easily exploitable by unauthenticated attackers over the network, potentially leading to a complete takeover of the affected system. The potential impacts on confidentiality, integrity, and availability are severe.

Unauthenticated network access can fully compromise Hyperion.
Executive oversight is needed for potential data control.
Confirm relevance and impact on your Hyperion systems.

Attack Path

How an attacker could exploit the issue

An unauthenticated attacker can exploit this vulnerability by sending a malicious request over the network to the Oracle Hyperion Infrastructure Technology's Common Events component. This could allow them to gain complete control over the affected system.

Attacker needs network access.
Triggered via HTTP to Common Events.
Complete system takeover is possible.

Live Threat

Current exploitation, exposure, and threat context

Frequently asked questions

What is Oracle Hyperion Infrastructure Technology?

Oracle Hyperion Infrastructure Technology is a foundational layer that supports Oracle Hyperion, a suite of business intelligence and financial performance management software. This component, specifically the Common Events module, manages internal messaging and task orchestration for the broader platform, enabling large-scale financial reporting and data analysis.

How does CVE-2026-62457 compromise the system?

This vulnerability represents a flaw where the system improperly handles incoming requests. An attacker can use this weakness to gain unauthorized, full control over the infrastructure. Because it affects core management components, a successful attack could result in the total compromise of system confidentiality, data integrity, and service availability.

Do I need to be authenticated to trigger this flaw?

No. The vulnerability does not require any prior user authentication or administrative credentials. Any attacker with network access to the target system can initiate the exploit. However, simply having network access is not enough if the system is isolated; the attacker must be able to send specifically crafted HTTP requests to the vulnerable Common Events component.

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

Halo Surface Signal indicates that while this is a network-based vulnerability, Oracle Hyperion is typically deployed in internal, protected environments rather than being exposed to the public internet. If your system is kept behind internal network controls or VPNs, the likelihood of a direct, external attack is reduced, though internal lateral movement remains a risk.

What should I do first to manage this risk?

Start by identifying all instances of version 11.2.25.0.000 within your environment. Once you have a clear inventory, determine which systems are business-critical and verify their current network accessibility. Finally, contact your internal system owners to coordinate a review of security controls and plan for the vendor-provided security updates.
