CVE-2026-70925: Oracle Hyperion Financial Management SQLI

CVE-2026-70925 Overview

CVE-2026-70925 is a high-severity vulnerability in the Security component of Oracle Hyperion Financial Management. The flaw affects version 11.2.25.0.000 and allows a low-privileged attacker with network access via SQL to compromise the application. Successful exploitation grants unauthorized read, create, delete, or modify access to critical data across the Oracle Hyperion Financial Management deployment. The weakness is classified under CWE-284: Improper Access Control. Oracle addressed the issue in the August 2026 security alert cycle.

Critical Impact
An authenticated attacker on the network can read, modify, or delete all data accessible to Oracle Hyperion Financial Management, breaking confidentiality and integrity of enterprise financial records.

Affected Products

Oracle Hyperion Financial Management 11.2.25.0.000
Oracle Hyperion product family (Security component)

Technical Details for CVE-2026-70925

Vulnerability Analysis

The vulnerability resides in the Security component of Oracle Hyperion Financial Management. According to the Oracle advisory, the flaw is easily exploitable and reachable over the network by an attacker holding low-privileged credentials. The attack channel is SQL, meaning the adversary interacts with the product's database-facing interfaces to bypass or subvert access controls.

Because the weakness maps to [CWE-284: Improper Access Control], the product fails to correctly restrict which authenticated principals can read or write specific data. Once the control is bypassed, the attacker gains the same reach as the compromised component across all Financial Management data.

Availability is not impacted, but confidentiality and integrity are fully compromised. Financial reporting environments typically hold consolidated ledger data, statutory reports, and forecasting models, making unauthorized modification a direct threat to reporting accuracy and audit posture.

Root Cause

Oracle attributes the issue to the Security component of Hyperion Financial Management. The improper access control condition permits a low-privileged network user to reach data operations that should require higher authorization, resulting in unauthorized create, read, update, and delete access. Oracle has not published implementation-level details beyond the Oracle Security Alert August 2026.

Attack Vector

The attack vector is network-based via SQL. The attacker must already hold low-level credentials on the Hyperion environment. No user interaction is required, and the scope is unchanged, meaning exploitation stays within the vulnerable component's authorization boundary. Refer to the Oracle Security Alert August 2026 for exposure guidance.

No public proof-of-concept, exploit code, or in-the-wild exploitation has been reported. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Detection Methods for CVE-2026-70925

Indicators of Compromise

Unexpected SQL sessions originating from low-privileged Hyperion application accounts against Financial Management schemas.
Unusual create, update, or delete operations on Financial Management metadata, consolidation rules, or journal tables outside change windows.
Access to security or entitlement tables by principals that do not normally require such access.

Detection Strategies

Enable database auditing on Hyperion Financial Management schemas and alert on privileged data-definition or data-manipulation statements issued by non-administrative accounts.
Baseline normal SQL activity per application service account and flag deviations in query patterns, target objects, or volume.
Correlate Hyperion application logs with database logs to identify SQL operations that were not initiated through supported application workflows.

Monitoring Recommendations

Forward Hyperion middleware, web tier, and database audit logs to a centralized analytics platform for retention and correlation.
Monitor authentication events for Hyperion low-privileged accounts, particularly logins from new hosts or off-hours access.
Track outbound data transfer volumes from Hyperion database hosts to detect bulk extraction of financial data.

How to Mitigate CVE-2026-70925

Immediate Actions Required

Apply the patches referenced in the Oracle Security Alert August 2026 to all Oracle Hyperion Financial Management 11.2.25.0.000 instances.
Inventory all Hyperion Financial Management deployments and confirm which are exposed to internal or external networks.
Review and reduce membership of low-privileged Hyperion roles until patching completes.

Patch Information

Oracle released fixes as part of the August 2026 Critical Patch Update cycle. Administrators should follow the remediation instructions in the Oracle Security Alert August 2026 and validate patch level after installation. Test patches in a non-production environment before promoting to production reporting systems.

Workarounds

Restrict network access to Hyperion Financial Management SQL and application endpoints using firewall rules or network segmentation.
Rotate credentials for low-privileged Hyperion accounts and enforce strong authentication for all users.
Increase database auditing on Financial Management schemas until the vendor patch is deployed.
