CVE-2026-62576 Overview
CVE-2026-62576 is a vulnerability in the Oracle Hyperion Infrastructure Technology product of Oracle Hyperion, specifically in the Installation and Configuration component. The affected supported version is 11.2.25.0.000. The flaw allows an unauthenticated attacker with network access via TLS to compromise the product, though successful exploitation is difficult. Successful attacks can result in unauthorized read access to critical data and unauthorized update, insert, or delete access to a subset of Oracle Hyperion Infrastructure Technology data.
Critical Impact
Unauthenticated network-based access can lead to disclosure of all accessible data and partial modification of stored data in Oracle Hyperion Infrastructure Technology.
Affected Products
- Oracle Hyperion Infrastructure Technology 11.2.25.0.000
- Component: Installation and Configuration
- Oracle Hyperion product family

Technical Details for CVE-2026-62576
Vulnerability Analysis
The vulnerability resides in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology. An unauthenticated attacker who can reach the product over the network via TLS can compromise the service without user interaction. Exploitation requires favorable conditions, reflected in the high attack complexity rating. The impact spans confidentiality of all accessible data and integrity of a subset of that data, while availability is not affected.
Oracle characterizes the exploitation path as difficult, which typically indicates dependence on specific configuration states, timing, or environmental factors within the Hyperion deployment. Because the Installation and Configuration component often handles bootstrap parameters, credentials, and service registration, a successful compromise can expose sensitive metadata that supports further movement into connected Hyperion services.
Root Cause
Oracle has not published detailed root cause information for CVE-2026-62576. The advisory identifies the defect within the Installation and Configuration component and indicates that the flaw is reachable by an unauthenticated network client communicating over TLS. See the Oracle Security Alert for the vendor's technical notes and patch mapping.
Attack Vector
The attack vector is network based over TLS. The attacker does not require prior authentication or user interaction. Because the scope is unchanged, exploitation affects only resources managed by the vulnerable component. The EPSS score is 0.219% with a percentile of 12.625, indicating a low modeled probability of exploitation activity in the near term.
No public proof-of-concept exploit code is available for CVE-2026-62576 at the time of writing. Refer to the vendor advisory for technical guidance rather than synthetic exploitation examples.
Detection Methods for CVE-2026-62576
Indicators of Compromise
- Unexpected read access to configuration files or provisioning data from Oracle Hyperion Infrastructure Technology hosts
- Unauthenticated TLS connections to Hyperion Installation and Configuration endpoints from unusual source addresses
- Anomalous modifications to Hyperion configuration records without a corresponding administrative session
Detection Strategies
- Enable detailed access logging on the Hyperion Installation and Configuration component and forward logs to a centralized analytics platform
- Alert on unauthenticated requests that succeed against configuration endpoints or return sensitive metadata
- Correlate TLS connection metadata with authentication events to identify sessions that bypass expected login flows
Monitoring Recommendations
- Baseline normal administrative traffic to Hyperion services and flag deviations in source, volume, or request pattern
- Monitor for outbound data transfers from Hyperion servers to untrusted destinations following configuration reads
- Track integrity of Hyperion configuration objects using file integrity monitoring and database change auditing
How to Mitigate CVE-2026-62576
Immediate Actions Required
- Apply the fixes referenced in the Oracle Security Alert for the August 2026 critical patch update
- Inventory Oracle Hyperion Infrastructure Technology deployments and identify all systems running version 11.2.25.0.000
- Restrict network exposure of Hyperion management interfaces to trusted administrative subnets
Patch Information
Oracle addressed CVE-2026-62576 as part of its scheduled security alerts. Administrators should consult the Oracle Security Alert for the specific patch bundle applicable to version 11.2.25.0.000 and follow Oracle's documented upgrade procedure for the Hyperion Infrastructure Technology stack.
Workarounds
- Place the Hyperion Installation and Configuration component behind a reverse proxy that enforces mutual TLS or IP allowlisting
- Segment Hyperion servers into a dedicated management VLAN with strict ingress firewall rules
- Disable or restrict access to configuration endpoints when they are not required for active administrative tasks
# Example: restrict inbound access to Hyperion management port using 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
