CVE-2026-62457 Overview
CVE-2026-62457 is a critical vulnerability in the Oracle Hyperion Infrastructure Technology product, specifically within the Common Events component. The affected version is 11.2.25.0.000. An unauthenticated attacker with network access via HTTP can exploit this flaw with low complexity. Successful exploitation results in full takeover of Oracle Hyperion Infrastructure Technology, impacting confidentiality, integrity, and availability.
Critical Impact
Unauthenticated remote attackers can compromise Oracle Hyperion Infrastructure Technology over the network without user interaction, leading to complete system takeover.

Technical Details for CVE-2026-62457
Vulnerability Analysis
The vulnerability resides in the Common Events component of Oracle Hyperion Infrastructure Technology. An attacker can reach the vulnerable component over HTTP without authentication or user interaction. Successful exploitation grants the attacker control over the affected instance, enabling data theft, data manipulation, and service disruption. Oracle categorizes this as easily exploitable, meaning weaponization does not require specialized conditions or elevated access.
Root Cause
Oracle's advisory identifies the flaw in the Common Events component but does not publicly disclose the underlying weakness class. The vulnerability profile is consistent with unauthenticated network-facing flaws in enterprise middleware that expose privileged operations without proper access control. See the Oracle Security Alert for authoritative technical details.
Attack Vector
The attack vector is network-based over HTTP. An attacker sends crafted requests to the exposed Hyperion Infrastructure Technology service. No credentials, prior access, or user interaction are required. Because the scope is unchanged and impact spans confidentiality, integrity, and availability, an attacker who successfully exploits the flaw can take full control of the target service.
No verified proof-of-concept code is publicly available. Refer to the Oracle Security Alert for technical details.
Detection Methods for CVE-2026-62457
Indicators of Compromise
- Unexpected HTTP requests targeting Oracle Hyperion Infrastructure Technology endpoints from external or unauthorized internal sources.
- Anomalous administrative activity, new user accounts, or configuration changes within Hyperion after unauthenticated network access.
- Outbound connections from the Hyperion host to unknown or suspicious infrastructure following inbound HTTP traffic.
Detection Strategies
- Inspect web server and application logs for malformed or unusual requests to the Common Events component.
- Correlate authentication events with process execution on the Hyperion host to identify post-exploitation activity.
- Deploy network intrusion detection signatures for known exploitation patterns once vendor detail is published.
Monitoring Recommendations
- Continuously monitor Oracle Hyperion middleware processes for unexpected child process creation.
- Alert on new listening ports, scheduled tasks, or service accounts created on Hyperion servers.
- Baseline HTTP traffic to Hyperion endpoints and alert on volumetric or structural deviations.
How to Mitigate CVE-2026-62457
Immediate Actions Required
- Apply the security update referenced in the Oracle Security Alert to affected Hyperion Infrastructure Technology deployments.
- Restrict network access to Hyperion Infrastructure Technology interfaces to trusted management networks only.
- Inventory all Hyperion 11.2.25.0.000 instances and prioritize internet-exposed systems for immediate remediation.
Patch Information
Oracle addresses this vulnerability in its August 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert for patch identifiers, applicability, and installation guidance for affected Hyperion components.
Workarounds
- Place Hyperion Infrastructure Technology behind a reverse proxy or web application firewall configured to block untrusted HTTP requests.
- Enforce network segmentation and firewall rules that limit access to the Common Events component to authorized hosts.
- Disable or isolate the affected component if immediate patching is not feasible until the update is applied.
# Example firewall restriction limiting HTTP access to Hyperion to a trusted subnet
iptables -A INPUT -p tcp --dport 19000 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 19000 -j DROP
