CVE-2026-62555: Oracle Hyperion SQLi Vulnerability

CVE-2026-62555 Overview

CVE-2026-62555 affects the Oracle Hyperion Infrastructure Technology product within Oracle Hyperion, specifically the Installation and Configuration component. The supported version affected is 11.2.25.0.000. The flaw allows a high-privileged attacker with network access via SQL to compromise Oracle Hyperion Infrastructure Technology. Successful exploitation can result in unauthorized creation, deletion, or modification of critical data, along with unauthorized read access to all data accessible by the product.

Critical Impact
A high-privileged attacker with network access via SQL can compromise the confidentiality and integrity of all Oracle Hyperion Infrastructure Technology accessible data.

Technical Details for CVE-2026-62555

Vulnerability Analysis

The vulnerability resides in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology. An authenticated attacker holding high privileges can send crafted SQL over the network to compromise the product. Successful exploitation grants the attacker full read access and the ability to create, delete, or modify any data accessible to the Hyperion Infrastructure Technology instance.

Because the attacker must already hold elevated privileges, this issue is most relevant in scenarios where a lower-trust operator or a compromised administrative account can escalate its reach across the Hyperion data tier. The Oracle advisory categorizes exploitation as easily achievable once the privilege prerequisite is met.

Root Cause

Oracle has not published detailed root-cause information beyond identifying the Installation and Configuration component and the SQL attack surface. The exposure allows privileged SQL-level operations to affect data confidentiality and integrity across the product scope. Refer to the Oracle Security Alert for vendor-authoritative details.

Attack Vector

Exploitation occurs over the network using SQL as the attack channel. The attacker must be authenticated with high privileges and does not require user interaction. Impact is limited to confidentiality and integrity; availability is not affected according to the CVSS vector published by Oracle.

Detection Methods for CVE-2026-62555

Indicators of Compromise

Unexpected SQL statements issued against Hyperion Infrastructure Technology databases by high-privileged accounts.
Unauthorized modifications to Hyperion configuration tables or installation metadata.
Anomalous data reads targeting Hyperion-accessible schemas outside normal administrative workflows.

Detection Strategies

Enable database auditing on Hyperion Infrastructure Technology backend databases to log privileged SQL activity.
Correlate administrative logins with subsequent SQL data manipulation language (DML) and data definition language (DDL) statements.
Baseline routine administrative SQL activity and alert on deviations, particularly bulk reads or schema changes.

Monitoring Recommendations

Forward Oracle database audit logs and Hyperion application logs to a centralized SIEM for correlation.
Monitor high-privileged service and administrator accounts for atypical query patterns across Hyperion environments.
Review access to the Installation and Configuration component and restrict it to a minimal set of maintenance windows and operators.

How to Mitigate CVE-2026-62555

Immediate Actions Required

Apply the fixes referenced in the Oracle Security Alert cspuaug2026 as soon as available.
Inventory Hyperion Infrastructure Technology deployments running version 11.2.25.0.000 and prioritize them for patching.
Review and reduce the number of accounts holding high privileges on Hyperion databases.

Patch Information

Oracle addresses this issue through its security alert program. Consult the Oracle Security Alert for the specific patch bundle applicable to Oracle Hyperion Infrastructure Technology 11.2.25.0.000.

Workarounds

Restrict network access to Hyperion database listeners so only trusted administrative hosts can initiate SQL sessions.
Enforce least-privilege on Hyperion administrative roles and rotate credentials for any accounts with elevated database access.
Enable database-level auditing and require multi-factor authentication for administrators managing Hyperion installations.

bash

# Example: restrict Oracle listener access to trusted management hosts
# /etc/hosts.allow style enforcement via sqlnet.ora
tcp.validnode_checking = yes
tcp.invited_nodes = (mgmt-host-1, mgmt-host-2)
tcp.excluded_nodes = (0.0.0.0/0)
