CVE-2026-87225 Overview
CVE-2026-87225 is a vulnerability in the Oracle Hyperion Financial Management product of Oracle Hyperion, specifically within the Security component. The affected supported version is 11.2.26.0.000. A low-privileged attacker with network access via HTTP can exploit this flaw to compromise Oracle Hyperion Financial Management. Successful exploitation grants unauthorized access to critical data or complete access to all Oracle Hyperion Financial Management accessible data. The attacker also gains the ability to cause a partial denial of service against the application.
Critical Impact
Authenticated attackers over the network can read all data accessible to Oracle Hyperion Financial Management and induce partial service disruption.
Affected Products
- Oracle Hyperion Financial Management 11.2.26.0.000
- Oracle Hyperion product family (Security component)
- Deployments exposing Hyperion Financial Management over HTTP

Technical Details for CVE-2026-87225
Vulnerability Analysis
The flaw resides in the Security component of Oracle Hyperion Financial Management. The vulnerability is classified as easily exploitable and requires only low-level authenticated access. Exploitation is performed over the network using HTTP, which aligns with Hyperion's standard web-facing deployment model. The confidentiality impact is high, indicating the attacker can access all data reachable by the Hyperion Financial Management service, including financial consolidation records, journals, and metadata. A secondary impact allows a partial denial of service, degrading availability of the financial reporting workflow without fully halting it. Integrity is not affected, so the attacker cannot modify records through this specific vector.
Root Cause
Oracle has not published a detailed technical root cause. Based on the component naming and impact profile, the weakness stems from improper access control within the Hyperion Security subsystem, allowing a low-privileged user to obtain data outside their assigned authorization scope. Refer to the Oracle Security Alert CSPUSEP2026 for authoritative details.
Attack Vector
An authenticated user with minimal role assignments sends crafted HTTP requests to the Hyperion Financial Management application. The Security component fails to enforce proper authorization on the targeted operations, returning sensitive data or triggering resource-intensive behavior. No user interaction is required, and the attack does not require elevated privileges or lateral movement prior to exploitation.
No verified public proof-of-concept code is available. Refer to the Oracle Security Alert CSPUSEP2026 for vendor-supplied technical details.
Detection Methods for CVE-2026-87225
Indicators of Compromise
- Unexpected HTTP request patterns from low-privileged Hyperion user accounts targeting Security or data-retrieval endpoints.
- Anomalous volumes of data export or report generation activity attributed to non-administrative Hyperion accounts.
- Repeated HTTP requests correlating with intermittent service slowdowns or partial availability degradation.
Detection Strategies
- Enable and forward Hyperion Financial Management application, HTTP access, and authentication logs to a centralized analytics platform.
- Baseline normal per-user query volumes and alert on deviations that suggest bulk data harvesting by standard users.
- Correlate Hyperion authentication events with downstream data access to identify low-privileged accounts retrieving privileged datasets.
Monitoring Recommendations
- Monitor HTTP endpoints associated with the Hyperion Security component for elevated 200 OK response volumes tied to individual sessions.
- Track application server CPU, memory, and thread utilization for partial denial-of-service indicators.
- Review Hyperion role assignments and audit any account performing operations inconsistent with its provisioned role.
How to Mitigate CVE-2026-87225
Immediate Actions Required
- Apply the fix referenced in the Oracle Security Alert CSPUSEP2026 to all Oracle Hyperion Financial Management 11.2.26.0.000 deployments.
- Restrict network reachability of Hyperion Financial Management to trusted internal segments and authenticated VPN users.
- Audit and reduce Hyperion user privileges, removing unnecessary low-tier accounts that could be abused.
Patch Information
Oracle addresses this vulnerability in the CSPUSEP2026 Security Alert. Administrators should download the corresponding patch package from My Oracle Support and apply it to affected Hyperion Financial Management 11.2.26.0.000 installations following Oracle's standard patch procedure. Validate the patch in a staging environment before production rollout to confirm compatibility with existing financial workflows.
Workarounds
- Place Hyperion Financial Management behind a web application firewall configured to inspect and rate-limit HTTP traffic to the Security component.
- Enforce strong authentication and short session lifetimes to reduce the exposure window for low-privileged accounts.
- Temporarily disable or restrict access for non-essential Hyperion user roles until the vendor patch is deployed.
