CVE-2026-62544 Overview
CVE-2026-62544 is a critical vulnerability in the Oracle Hyperion Infrastructure Technology product of Oracle Hyperion, specifically within the Installation and Configuration component. The affected supported version is 11.2.25.0.000. An unauthenticated attacker with network access via HTTP can exploit this flaw with low complexity and no user interaction. Successful exploitation results in full takeover of Oracle Hyperion Infrastructure Technology, impacting confidentiality, integrity, and availability.
Critical Impact
Remote, unauthenticated attackers can achieve complete compromise of Oracle Hyperion Infrastructure Technology deployments over HTTP.
Affected Products
- Oracle Hyperion Infrastructure Technology 11.2.25.0.000
- Component: Installation and Configuration
- Deployments exposing the Hyperion HTTP interfaces to untrusted networks
Discovery Timeline

Technical Details for CVE-2026-62544
Vulnerability Analysis
The flaw resides in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology. Oracle's advisory describes the issue as easily exploitable, requiring only network access over HTTP and no prior authentication. Successful exploitation yields takeover of the Hyperion Infrastructure Technology instance, meaning an attacker can read, modify, and disrupt the platform's data and services.
Because Hyperion Infrastructure Technology underpins enterprise performance management workloads, compromise can pivot into downstream reporting, financial consolidation, and planning applications. The EPSS probability is 0.486% at the 39.989 percentile as of 2026-08-20, indicating measurable but not yet widespread exploitation forecasting.
Root Cause
Oracle has not published detailed root-cause information beyond the advisory. The CVSS vector and "Installation and Configuration" scope point to a pre-authentication defect in an HTTP-exposed setup or configuration endpoint. Refer to the Oracle Security Alert for vendor-supplied technical details.
Attack Vector
The attack is network-based over HTTP. No credentials, privileges, or user interaction are required. An attacker who can reach the Hyperion HTTP listener can issue crafted requests to the vulnerable Installation and Configuration component and take control of the service. See the Oracle Security Alert for advisory details. No public proof-of-concept exploit code has been released at the time of this writing.
Detection Methods for CVE-2026-62544
Indicators of Compromise
- Unexpected HTTP requests targeting Hyperion Installation and Configuration endpoints from external or non-administrative source addresses.
- New or modified administrative accounts, scheduled tasks, or service configurations on Hyperion middleware hosts.
- Outbound connections from Hyperion servers to unfamiliar IP addresses shortly after inbound HTTP activity.
Detection Strategies
- Baseline normal HTTP traffic to Hyperion services and alert on anomalous URIs or POST bodies aimed at configuration paths.
- Correlate web server access logs with process creation and file modification events on Hyperion middleware hosts.
- Monitor for command interpreter spawns (cmd.exe, powershell.exe, /bin/sh) parented by Hyperion or WebLogic-related processes.
Monitoring Recommendations
- Forward Hyperion HTTP access logs, WebLogic logs, and host telemetry to a centralized analytics platform for correlation.
- Track configuration file changes on Hyperion servers and alert on modifications outside approved change windows.
- Review authentication and privilege changes in surrounding identity systems for lateral-movement indicators.
How to Mitigate CVE-2026-62544
Immediate Actions Required
- Apply the Oracle Critical Patch Update referenced in the Oracle Security Alert to affected Hyperion 11.2.25.0.000 deployments.
- Restrict network access to Hyperion HTTP interfaces so only trusted administrative networks can reach them.
- Audit Hyperion middleware hosts for unauthorized accounts, configuration changes, or persistence artifacts.
Patch Information
Oracle addresses this vulnerability in the August 2026 Critical Patch Update cycle. Administrators should download the applicable patches from the Oracle Security Alert page and apply them to the affected supported version 11.2.25.0.000 following Oracle's documented upgrade procedures.
Workarounds
- Place Hyperion HTTP endpoints behind a reverse proxy or web application firewall that enforces authentication and IP allow-listing.
- Disable or firewall off the Installation and Configuration component from untrusted network segments until patches are applied.
- Enforce network segmentation between Hyperion middleware tiers and general-purpose user networks to limit exposure.
