CVE-2026-62500 Overview
CVE-2026-62500 affects the Oracle Hyperion Infrastructure Technology product within Oracle Hyperion, specifically the Common Events component. The affected version is 11.2.25.0.000. An attacker with low privileges and network access over HTTP can exploit this flaw to compromise the affected system. Successful exploitation results in a full takeover of Oracle Hyperion Infrastructure Technology, impacting confidentiality, integrity, and availability. Oracle disclosed the issue in its August 2026 Security Alert.
Critical Impact
Authenticated network-based attackers can take over Oracle Hyperion Infrastructure Technology, compromising sensitive financial and enterprise performance management data.

Technical Details for CVE-2026-62500
Vulnerability Analysis
The vulnerability resides in the Common Events component of Oracle Hyperion Infrastructure Technology. Oracle classifies the flaw as easily exploitable by an authenticated attacker communicating over HTTP. Because the confidentiality, integrity, and availability impacts are all rated high, the flaw enables complete compromise of the Hyperion Infrastructure Technology stack.
Oracle Hyperion Infrastructure Technology underpins enterprise financial planning, consolidation, and reporting workflows. A takeover exposes financial records, budget data, and administrative controls to unauthorized manipulation. The scope remains unchanged, meaning the attack affects only the vulnerable component, but that component holds sensitive enterprise data.
Root Cause
Oracle has not published detailed root cause information in the public advisory. The Common Events subsystem processes event notifications between Hyperion services, and a flaw in how it handles authenticated HTTP requests permits privilege abuse. Refer to the Oracle Security Alert August 2026 for vendor-provided technical context.
Attack Vector
The attacker requires network reachability to the Hyperion HTTP endpoints and a low-privileged account within the environment. No user interaction is needed. After authenticating, the attacker sends crafted requests to the Common Events component to escalate control over the platform. The EPSS probability is 0.447%, indicating low current exploitation likelihood but the impact justifies prompt remediation.
Exploitation code details are not published. Consult Oracle's Critical Patch Update material for further technical information rather than relying on synthetic proof-of-concept content.
Detection Methods for CVE-2026-62500
Indicators of Compromise
- Unexpected authenticated HTTP requests directed at Hyperion Common Events endpoints from low-privileged service accounts.
- New or modified administrative accounts within Hyperion Shared Services following anomalous session activity.
- Unusual outbound connections or data exports originating from Hyperion Infrastructure Technology hosts.
Detection Strategies
- Enable verbose HTTP access logging on Oracle HTTP Server and Hyperion Foundation Services to capture request paths and payload metadata.
- Correlate authentication events with subsequent privileged operations to identify anomalous escalation patterns.
- Baseline expected Common Events traffic and alert on deviations in request volume, source, or endpoint targeting.
Monitoring Recommendations
- Forward Hyperion, WebLogic, and OHS logs into a centralized SIEM for continuous analysis.
- Monitor administrative changes in Hyperion Shared Services and correlate them with recent HTTP session activity.
- Track process, file, and registry activity on Hyperion servers to detect post-exploitation behavior.
How to Mitigate CVE-2026-62500
Immediate Actions Required
- Apply Oracle's August 2026 security patches for Oracle Hyperion Infrastructure Technology without delay.
- Restrict network access to Hyperion HTTP endpoints to trusted management networks only.
- Audit Hyperion user accounts and remove unused or over-privileged credentials that could be leveraged for low-privileged exploitation.
Patch Information
Oracle addressed CVE-2026-62500 in the Oracle Security Alert August 2026. Administrators running Oracle Hyperion Infrastructure Technology 11.2.25.0.000 should follow Oracle's patch application guidance and validate deployment against the Critical Patch Update advisory.
Workarounds
- Place Hyperion Infrastructure Technology behind a reverse proxy or web application firewall that enforces strict authentication and rate limits.
- Segment Hyperion servers on a dedicated VLAN with tight ingress controls until patching is complete.
- Enforce multi-factor authentication and rotate credentials for all Hyperion service and administrative accounts.
# Example: restrict HTTP access to Hyperion endpoints via iptables
iptables -A INPUT -p tcp --dport 19000 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 19000 -j DROP
