CVE-2026-70824 Overview
CVE-2026-70824 is an information disclosure vulnerability in Oracle Hyperion Financial Management, part of the Oracle Hyperion product family. The flaw resides in the Security component of version 11.2.25.0.000. A low-privileged attacker with network access via HTTP can exploit this vulnerability without user interaction. Successful exploitation results in unauthorized access to critical data or complete access to all data reachable through Oracle Hyperion Financial Management. Oracle published the vulnerability in its August 2026 Critical Patch Update Security Alert.
Critical Impact
Authenticated attackers with minimal privileges can read all data accessible to Oracle Hyperion Financial Management over the network, exposing sensitive financial reporting information.
Affected Products
- Oracle Hyperion Financial Management 11.2.25.0.000
- Oracle Hyperion (Security component)
- Deployments exposing Hyperion Financial Management endpoints over HTTP

Technical Details for CVE-2026-70824
Vulnerability Analysis
The vulnerability affects the Security component of Oracle Hyperion Financial Management 11.2.25.0.000. It exposes confidential data to authenticated users who should not have broad read access to the application's data. The impact is limited to confidentiality; integrity and availability of the system are not affected by this issue. Oracle categorizes the flaw as easily exploitable because the attacker only needs low privileges and network reachability to the HTTP service. Hyperion Financial Management processes consolidated financial data, so unauthorized read access can expose earnings figures, intercompany transactions, and reporting hierarchies before public disclosure.
Root Cause
Oracle's advisory identifies the Security component as the affected subsystem but does not publish detailed root-cause information. The behavior is consistent with a broken access control weakness where authorization checks fail to constrain what data a low-privileged user can retrieve. Refer to the Oracle Security Alert for vendor-provided technical context.
Attack Vector
An attacker requires authenticated access to the Hyperion Financial Management application with low privileges. The attacker sends crafted HTTP requests to endpoints exposed by the Security component. Because the attack complexity is low and no user interaction is required, exploitation can be scripted and repeated to enumerate accessible data. Internet-facing Hyperion deployments and multi-tenant environments where many users share a Hyperion instance carry the highest exposure.
No public proof-of-concept code is available. Refer to the Oracle Security Alert for vendor-provided technical details.
Detection Methods for CVE-2026-70824
Indicators of Compromise
- Unusual volume of HTTP requests to Hyperion Financial Management endpoints from a single authenticated user account
- Access patterns where low-privileged accounts retrieve data outside their assigned application security class or entity scope
- Session activity originating from IP addresses not associated with normal finance-team workstations
Detection Strategies
- Enable and review Hyperion Financial Management application audit logs for Data, Rules, and Task access events tied to low-privileged users
- Correlate web server access logs with Hyperion user roles to identify requests that return data volumes inconsistent with the user's role
- Baseline normal query patterns per user role and alert on statistical outliers in retrieval size or frequency
Monitoring Recommendations
- Forward Hyperion Financial Management audit logs and IIS or web tier logs to a centralized log platform for retention and query
- Monitor authentication events for stale, service, or shared accounts that access Hyperion resources outside business hours
- Track configuration changes to Security component roles and provisioning to detect privilege modifications preceding suspicious access
How to Mitigate CVE-2026-70824
Immediate Actions Required
- Apply the patch referenced in the Oracle August 2026 Critical Patch Update Security Alert to Hyperion Financial Management 11.2.25.0.000
- Inventory all Hyperion Financial Management instances, including non-production environments, and prioritize internet-facing deployments
- Review user provisioning and remove low-privileged accounts that are inactive, shared, or no longer required
Patch Information
Oracle addressed CVE-2026-70824 in the August 2026 Critical Patch Update Security Alert. Administrators should download and apply the fix per Oracle's advisory guidance in the Oracle Security Alert. Validate the patch in a non-production environment before rolling it into production financial close cycles.
Workarounds
- Restrict network access to Hyperion Financial Management HTTP endpoints using firewall rules or a reverse proxy that limits source IPs to trusted finance-team subnets
- Enforce multi-factor authentication on all Hyperion user accounts to reduce the risk of low-privileged credential abuse
- Review and tighten application security classes so that low-privileged roles cannot query data outside their business scope
- Increase audit log retention and monitoring frequency until the patch is fully deployed across all instances
