CVE-2026-70744 Overview
CVE-2026-70744 is a network-exploitable vulnerability in the Server component of Oracle Hyperion Financial Reporting. The flaw affects supported version 11.2.25.0.000 and can be reached over HTTP without authentication. Oracle documents the issue in the Oracle Security Alert Advisory.
Successful exploitation results in full takeover of Oracle Hyperion Financial Reporting, with impact on confidentiality, integrity, and availability. Oracle notes that exploitation is difficult, but no privileges or user interaction are required.
Critical Impact
An unauthenticated attacker with HTTP access to the Hyperion Financial Reporting Server can achieve complete product takeover, exposing sensitive financial data and reporting workflows.
Affected Products
- Oracle Hyperion Financial Reporting 11.2.25.0.000
- Oracle Hyperion product family (Server component)
- Deployments exposing the Hyperion Financial Reporting HTTP interface

Technical Details for CVE-2026-70744
Vulnerability Analysis
The vulnerability resides in the Server component of Oracle Hyperion Financial Reporting, which handles HTTP requests for reporting operations. An unauthenticated remote attacker can send crafted network traffic to the server and gain control of the application.
Oracle categorizes the issue as difficult to exploit, indicating that specific preconditions or timing must be met. However, once those conditions are satisfied, the attacker fully compromises confidentiality, integrity, and availability of the reporting service. The scope remains unchanged, meaning impact is contained within the vulnerable Hyperion component rather than extending across trust boundaries.
EPSS data assigns this CVE a probability of 0.376% with a percentile of 30.969, reflecting that no public exploit is currently observed in the wild.
Root Cause
Oracle's advisory does not disclose the internal defect. The vulnerability is reachable through the HTTP-facing Server component, which suggests improper handling of untrusted input during request processing. Because no authentication is required, the flaw sits before or within the request authorization path.
Attack Vector
The attack vector is network-based over HTTP. An attacker with reachability to the Hyperion Financial Reporting HTTP endpoint can submit malicious requests without credentials or user interaction. Environments exposing Hyperion to internal enterprise networks, DMZs, or partner links present the largest attack surface. See the Oracle Security Alert for vendor guidance.
No verified proof-of-concept exploit is publicly available at the time of publication. Technical exploitation details are not disclosed in the advisory.
Detection Methods for CVE-2026-70744
Indicators of Compromise
- Anomalous HTTP POST or GET requests to Hyperion Financial Reporting endpoints from unexpected internal or external sources.
- New administrative user accounts, scheduled reports, or configuration changes on the Hyperion server without an approved change ticket.
- Outbound network connections initiated by the Hyperion Financial Reporting service process to untrusted hosts.
Detection Strategies
- Baseline normal HTTP traffic patterns to the Hyperion Financial Reporting Server and alert on request volume spikes or unusual URI patterns.
- Monitor Hyperion application and web server logs for authentication anomalies, unexpected 5xx responses, and repeated malformed requests.
- Correlate process execution telemetry on Hyperion hosts with child processes spawned by the Java application server, which may indicate post-exploitation activity.
Monitoring Recommendations
- Forward Hyperion Financial Reporting Server logs, host EDR telemetry, and web proxy logs to a centralized SIEM for correlation.
- Enable file integrity monitoring on Hyperion configuration directories, deployment artifacts, and report templates.
- Track outbound connections from the Hyperion server against threat intelligence feeds to identify command-and-control activity.
How to Mitigate CVE-2026-70744
Immediate Actions Required
- Apply the Oracle Critical Patch Update referenced in the Oracle Security Alert as soon as testing allows.
- Restrict network access to the Hyperion Financial Reporting Server so only authorized management networks and application clients can reach the HTTP interface.
- Inventory all Hyperion Financial Reporting 11.2.25.0.000 instances, including non-production environments, and prioritize remediation on internet-adjacent hosts.
Patch Information
Oracle addresses CVE-2026-70744 through the security update published in the August 2026 Oracle Security Alert. Administrators should review the advisory for the exact patch identifier applicable to Oracle Hyperion Financial Reporting 11.2.25.0.000 and follow Oracle's documented patching procedure for the Hyperion product family.
Workarounds
- Place the Hyperion Financial Reporting Server behind a reverse proxy or web application firewall with strict allowlists for source IPs and URI paths.
- Disable or firewall unused HTTP endpoints on the Hyperion Server until the vendor patch is deployed.
- Enforce network segmentation so the Hyperion host cannot initiate arbitrary outbound connections to the internet.
