CVE-2026-62522 Overview
CVE-2026-62522 is a high-severity vulnerability in the Oracle Hyperion Infrastructure Technology product of Oracle Hyperion, specifically within the Common Security component. The affected version is 11.2.25.0.000. A low-privileged attacker with network access via HTTP can exploit this flaw, though exploitation is considered difficult. Successful attacks result in unauthorized access to critical data and unauthorized update, insert, or delete access to some Oracle Hyperion Infrastructure Technology data. The vulnerability has a scope change, meaning attacks may significantly impact additional products beyond Oracle Hyperion Infrastructure Technology itself.
Critical Impact
Attackers can gain unauthorized access to all Oracle Hyperion Infrastructure Technology accessible data and modify a subset of that data, with cross-product impact due to the scope change.
Affected Products
- Oracle Hyperion Infrastructure Technology 11.2.25.0.000
- Oracle Hyperion (Common Security component)
- Additional Oracle products affected by scope change per Oracle Security Alert

Technical Details for CVE-2026-62522
Vulnerability Analysis
The vulnerability resides in the Common Security component of Oracle Hyperion Infrastructure Technology. An authenticated attacker holding low privileges can send crafted HTTP requests to the affected service. Successful exploitation yields high confidentiality impact and low integrity impact, while availability remains unaffected.
The scope change indicates that the vulnerable component and the impacted component differ in their security authority. An attacker who compromises the Common Security layer can pivot into resources managed by other Oracle Hyperion components. This escalates the practical blast radius beyond the initially exploited service.
The HIGH attack complexity reflects conditions outside the attacker's control, such as timing, configuration, or prerequisite information required to weaponize the flaw reliably.
Root Cause
Oracle has not publicly disclosed the underlying weakness class or CWE identifier. Based on the Common Security component context and the observed impact pattern, the flaw affects authentication or authorization enforcement mechanisms shared across Hyperion services. Refer to the Oracle Security Alert for vendor-supplied technical context.
Attack Vector
Attackers exploit this vulnerability remotely over HTTP. The attacker requires low-level authenticated access to the target Hyperion environment. No user interaction is needed. Because the scope changes upon successful exploitation, the attacker can reach data managed by adjacent Oracle products relying on the shared security infrastructure.
The vulnerability manifests within Oracle's proprietary Common Security code path. No public proof-of-concept exploit exists at time of writing, and the flaw is not listed in the CISA Known Exploited Vulnerabilities catalog. See the Oracle Security Alert for authoritative details.
Detection Methods for CVE-2026-62522
Indicators of Compromise
- Unexpected HTTP requests to Oracle Hyperion Common Security endpoints from low-privileged accounts
- Anomalous authentication or authorization events tied to Hyperion Infrastructure Technology service accounts
- Cross-product data access patterns from Hyperion service identities into adjacent Oracle products
Detection Strategies
- Enable and centralize HTTP access logs from Oracle Hyperion Infrastructure Technology 11.2.25.0.000 instances
- Baseline normal Hyperion Common Security request patterns and alert on deviations in request volume, method, or endpoint
- Correlate Hyperion authentication events with downstream data access in adjacent Oracle products to surface scope-change abuse
Monitoring Recommendations
- Ingest Oracle Hyperion application, WebLogic, and OS logs into a centralized SIEM for correlation
- Monitor administrative and service accounts for privilege use outside documented workflows
- Track outbound queries and data volumes from Hyperion Infrastructure Technology hosts to identify bulk exfiltration attempts
How to Mitigate CVE-2026-62522
Immediate Actions Required
- Apply Oracle's August 2026 Critical Patch Update to affected Oracle Hyperion Infrastructure Technology deployments
- Inventory all Hyperion 11.2.25.0.000 installations and confirm patch status
- Restrict HTTP access to Hyperion Common Security endpoints to trusted management networks only
- Rotate credentials for any low-privileged accounts with access to Hyperion services following patching
Patch Information
Oracle addressed this vulnerability in the August 2026 Critical Patch Update / Security Alert. Administrators must apply the vendor-supplied patch referenced in the Oracle Security Alert. Oracle does not support unpatched deployments for production environments handling sensitive financial and planning data.
Workarounds
- Enforce network segmentation to limit HTTP reachability of Hyperion Infrastructure Technology to authorized users only
- Apply least-privilege reviews to remove unused low-privileged accounts on Hyperion services
- Enable web application firewall rules to inspect and rate-limit requests to Common Security endpoints pending patch deployment
# Restrict HTTP access to Hyperion Common Security endpoints at the network layer
# Example iptables rule allowing only trusted management 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
