CVE-2026-70793: Oracle Hyperion Financial Reporting SQLi

CVE-2026-70793 Overview

CVE-2026-70793 is a medium-severity vulnerability affecting Oracle Hyperion Financial Reporting, part of the Oracle Hyperion product family. The flaw resides in the Server component and impacts version 11.2.25.0.000. An authenticated attacker with low privileges can exploit the issue over the network using HTTP. Successful exploitation allows unauthorized update, insert, or delete access to a subset of accessible data, as well as unauthorized read access to a subset of accessible data. Oracle disclosed the issue in its August 2026 Critical Patch Update Advisory.

Critical Impact
Authenticated network attackers can modify and read a subset of Oracle Hyperion Financial Reporting data, undermining the integrity and confidentiality of financial reporting workflows.

Affected Products

Oracle Hyperion Financial Reporting 11.2.25.0.000
Oracle Hyperion (Server component)
Deployments exposing the Financial Reporting HTTP interface to authenticated users

Technical Details for CVE-2026-70793

Vulnerability Analysis

The vulnerability affects the Server component of Oracle Hyperion Financial Reporting. Oracle classifies exploitation as difficult, meaning specialized conditions must be met beyond attacker control. An attacker requires network access via HTTP and valid low-privileged credentials to reach the vulnerable endpoint. Once exploited, the flaw permits partial modification of stored data alongside partial read access to accessible datasets. Availability is not affected, and the scope of the compromise remains within the vulnerable component.

Oracle has not published low-level technical details, and no Common Weakness Enumeration (CWE) mapping is currently associated with the entry. The Exploit Prediction Scoring System (EPSS) probability is 0.165%, indicating a low near-term likelihood of observed exploitation. No public proof-of-concept or exploit code is available at the time of publication.

Root Cause

Oracle's advisory attributes the issue to the Financial Reporting Server component but does not disclose the underlying code defect. Based on the CVSS metrics, the flaw most likely stems from insufficient authorization enforcement or input validation on an HTTP-accessible interface accessed by authenticated users.

Attack Vector

Exploitation requires network reachability to the Hyperion Financial Reporting HTTP service and a valid low-privileged account. The attacker sends crafted HTTP requests to the vulnerable Server component. Because the attack complexity is high, successful exploitation depends on conditions such as timing, configuration state, or specific data prerequisites.

No verified exploit code is available. Refer to the Oracle Security Alert for the vendor's technical guidance.

Detection Methods for CVE-2026-70793

Indicators of Compromise

Unexpected update, insert, or delete operations against Financial Reporting data by low-privileged accounts
HTTP requests to Financial Reporting Server endpoints originating from unusual source IPs or user agents
Anomalous session activity correlated with data modifications outside normal business hours

Detection Strategies

Enable verbose HTTP access logging on the Hyperion Financial Reporting Server and forward logs to a centralized SIEM
Baseline normal Financial Reporting user activity and alert on deviations in request volume, endpoints accessed, or write operations
Correlate authentication events with data modification events to identify low-privileged accounts performing unexpected writes

Monitoring Recommendations

Monitor Oracle Hyperion audit logs for changes to reports, folders, and metadata by non-administrative users
Track failed and successful authentication attempts against Hyperion services for brute-force or credential-stuffing patterns
Alert on any deployment still running Financial Reporting version 11.2.25.0.000 after the vendor patch is available

How to Mitigate CVE-2026-70793

Immediate Actions Required

Review the Oracle Security Alert and identify all Hyperion Financial Reporting instances running affected versions
Apply the patches from the Oracle August 2026 Critical Patch Update as soon as change control permits
Audit low-privileged Hyperion accounts and revoke unused or excess access

Patch Information

Oracle released the fix as part of its August 2026 Critical Patch Update Advisory. Administrators should reference the Oracle Security Alert for patch download instructions and supported upgrade paths from version 11.2.25.0.000.

Workarounds

Restrict network access to the Hyperion Financial Reporting Server using firewall rules or reverse proxy allowlists
Enforce multi-factor authentication (MFA) on all Hyperion user accounts to reduce credential abuse risk
Apply the principle of least privilege to Financial Reporting roles and remove unnecessary write permissions

bash

# Configuration example: restrict Hyperion Financial Reporting HTTP access to trusted subnets
iptables -A INPUT -p tcp --dport 8200 -s 10.10.0.0/16 -j ACCEPT
iptables -A INPUT -p tcp --dport 8200 -j DROP
