CVE-2026-62532: Oracle Hyperion SQLi Vulnerability

CVE-2026-62532 Overview

CVE-2026-62532 is a vulnerability in the Oracle Hyperion Calculation Manager product of Oracle Hyperion, within the Security component. The affected supported version is 11.2.25.0.000. The flaw allows a high-privileged attacker with network access via SQL to compromise Oracle Hyperion Calculation Manager. Successful exploitation can result in unauthorized update, insert, or delete access to some accessible data, and unauthorized read access to a subset of data. Oracle addressed the issue in the August 2026 Critical Patch Update.

Critical Impact
A high-privileged network attacker can achieve limited unauthorized read, update, insert, or delete access to Oracle Hyperion Calculation Manager data via SQL.

Technical Details for CVE-2026-62532

Vulnerability Analysis

The vulnerability resides in the Security component of Oracle Hyperion Calculation Manager. An authenticated attacker holding high privileges can send crafted SQL over a network channel to interact with the application in unintended ways. The impact scope is limited to partial confidentiality and integrity effects on data reachable by Calculation Manager. Availability is not affected, and no user interaction is required to trigger the flaw.

Root Cause

Oracle's advisory categorizes the flaw under the Security component and describes the attack path as SQL over a network vector. The technical specifics of the underlying defect have not been disclosed publicly by Oracle. Based on the described impacts, the weakness permits privileged SQL operations that bypass intended data access boundaries. Consult the Oracle Security Alert August 2026 for authoritative technical details.

Attack Vector

Exploitation requires network reachability to the Oracle Hyperion Calculation Manager service and pre-existing high-privilege authentication. Attack complexity is low and no user interaction is required. Once authenticated, the attacker issues SQL-level operations that yield unauthorized read access to a subset of accessible data and unauthorized modification of some data. The scope is unchanged, meaning impact is contained within the Calculation Manager security boundary.

No verified proof-of-concept code has been published. Refer to the Oracle Critical Patch Update advisory for exploitation constraints and fix details.

Detection Methods for CVE-2026-62532

Indicators of Compromise

Unexpected SQL statements originating from privileged Hyperion Calculation Manager accounts against backend databases.
Unauthorized modifications (insert, update, delete) to Calculation Manager configuration or rule data tables.
Read access patterns targeting Calculation Manager metadata outside normal business workflows.

Detection Strategies

Enable and review database audit logging on the Hyperion repository schema, focusing on privileged accounts.
Correlate application-tier authentication events with backend SQL activity to identify anomalous privileged sessions.
Baseline normal Calculation Manager query patterns and alert on deviations in scope or frequency.

Monitoring Recommendations

Forward Oracle Hyperion application logs and database audit trails into a centralized SIEM for retention and correlation.
Monitor network traffic to the Calculation Manager service for unusual client sources or off-hours activity.
Track administrative account usage and enforce alerts on data-changing SQL statements executed outside change windows.

How to Mitigate CVE-2026-62532

Immediate Actions Required

Apply the fixes from the Oracle Security Alert August 2026 to affected Hyperion Calculation Manager 11.2.25.0.000 deployments.
Inventory Hyperion Calculation Manager instances and confirm patch coverage across production and non-production environments.
Review and reduce the number of high-privileged accounts able to reach Calculation Manager over the network.

Patch Information

Oracle addressed CVE-2026-62532 in the August 2026 Critical Patch Update. Administrators should download and apply the patch bundle referenced in the Oracle Security Alert August 2026 advisory. Test the update in a staging environment prior to production rollout.

Workarounds

Restrict network access to Oracle Hyperion Calculation Manager to trusted administrative subnets only.
Enforce least-privilege on Hyperion administrative roles and rotate credentials for accounts with high privileges.
Enable database-level auditing for the Hyperion repository until patching is complete.

bash

# Configuration example
# Restrict Calculation Manager access at the network layer (illustrative iptables rule)
iptables -A INPUT -p tcp --dport 19000 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 19000 -j DROP
