CVE-2026-62471 Overview
CVE-2026-62471 affects the Oracle Hyperion Infrastructure Technology product within the Oracle Hyperion suite. The flaw resides in the Common Events component of version 11.2.25.0.000. An unauthenticated attacker with network access over HTTP can exploit the weakness to compromise the affected system. Successful exploitation results in full takeover of Oracle Hyperion Infrastructure Technology, impacting confidentiality, integrity, and availability. Oracle addressed the issue in the Oracle Security Alert August 2026.
Critical Impact

Technical Details for CVE-2026-62471
Vulnerability Analysis
The vulnerability resides in the Common Events component of Oracle Hyperion Infrastructure Technology. Oracle's advisory classifies exploitation as difficult, indicating that specific conditions outside the attacker's control must be met. Despite this exploitation complexity, no authentication or user interaction is required for a successful attack.
The attack surface is exposed over HTTP, making the flaw reachable by any network-adjacent adversary that can send crafted requests to a Hyperion deployment. Successful exploitation results in a full compromise of the Hyperion Infrastructure Technology instance, giving attackers control over financial planning, consolidation, and reporting workloads that Hyperion typically hosts.
Root Cause
Oracle has not published detailed root cause information for CVE-2026-62471. The advisory attributes the weakness to the Common Events component, which handles event processing across Hyperion Infrastructure Technology services. Refer to the Oracle Security Alert August 2026 for authoritative details.
Attack Vector
The attack vector is network-based over HTTP. An unauthenticated attacker sends crafted HTTP requests to the exposed Hyperion service to trigger the flaw in the Common Events component. Because Hyperion deployments frequently sit on internal enterprise networks, exposure to the internet or lateral access from a compromised host increases realistic exploitation risk. No public proof-of-concept code has been published for this vulnerability at the time of writing.
Detection Methods for CVE-2026-62471
Indicators of Compromise
- Unexpected HTTP POST or GET requests to Oracle Hyperion Infrastructure Technology endpoints from unauthenticated sources
- Anomalous process creation or child processes spawned by Hyperion service accounts
- Unusual outbound network connections from Hyperion application servers following inbound HTTP traffic
Detection Strategies
- Monitor Hyperion application and web server logs for malformed or unusual requests targeting the Common Events component
- Baseline normal Hyperion administrative activity and alert on deviations, particularly unauthenticated access attempts
- Correlate authentication logs with process telemetry on Hyperion hosts to detect post-exploitation activity
Monitoring Recommendations
- Ingest Hyperion middle-tier and web server logs into a centralized logging platform for retention and analysis
- Deploy endpoint telemetry on all Hyperion Infrastructure Technology servers to capture process, file, and network activity
- Alert on new service accounts, scheduled tasks, or persistence mechanisms created on Hyperion hosts
How to Mitigate CVE-2026-62471
Immediate Actions Required
- Apply the patches referenced in the Oracle Security Alert August 2026 to all Oracle Hyperion Infrastructure Technology 11.2.25.0.000 deployments
- Inventory all Hyperion instances and confirm patch status through configuration management
- Restrict network access to Hyperion HTTP endpoints to trusted management networks only
- Review Hyperion service account activity and administrative logs for signs of prior exploitation
Patch Information
Oracle published fixes for CVE-2026-62471 as part of the Oracle Security Alert August 2026. Administrators should follow Oracle's Critical Patch Update guidance to apply the corresponding patch to Oracle Hyperion Infrastructure Technology 11.2.25.0.000. Consult the Oracle Security Alert August 2026 for the authoritative patch download and deployment instructions.
Workarounds
- Place Hyperion Infrastructure Technology behind a web application firewall configured to inspect and filter traffic to Common Events endpoints
- Segment Hyperion servers on isolated VLANs and require VPN or bastion access for administrative connectivity
- Disable or restrict any externally reachable Hyperion HTTP listeners until patching is complete
