CVE-2026-62577 Overview
CVE-2026-62577 affects the Oracle Hyperion Infrastructure Technology product within the Oracle Hyperion suite, specifically the Installation and Configuration component. The affected supported version is 11.2.25.0.000. A low-privileged attacker with local logon access to the infrastructure running Oracle Hyperion Infrastructure Technology can exploit the flaw to gain unauthorized update, insert, or delete access to a subset of product data. Oracle disclosed the issue in its August 2026 security advisory.
Critical Impact
Successful exploitation allows a local, authenticated attacker to modify, insert, or delete Oracle Hyperion Infrastructure Technology data, undermining data integrity.
Affected Products
- Oracle Hyperion Infrastructure Technology 11.2.25.0.000
- Component: Installation and Configuration
- Oracle Hyperion product family

Technical Details for CVE-2026-62577
Vulnerability Analysis
The vulnerability resides in the Installation and Configuration component of Oracle Hyperion Infrastructure Technology. It permits an authenticated user with local access to alter data managed by the product without proper authorization checks. The scope is unchanged, meaning the impact is limited to resources managed by the vulnerable component. Confidentiality and availability are not affected; only integrity is degraded through unauthorized write operations.
Because exploitation requires local access and low privileges, the practical attack surface is narrower than a remotely exploitable flaw. However, environments where multiple administrators, operators, or service accounts share access to Hyperion infrastructure hosts should treat the issue as material to data governance and audit integrity. The EPSS probability of 0.108% reflects a low predicted likelihood of exploitation in the wild.
Root Cause
Oracle has not disclosed low-level technical details beyond the advisory description. The vector indicates that a low-privileged local user can bypass integrity controls in the Installation and Configuration component, allowing write access to data the user should not be permitted to modify. This is consistent with an Improper Access Control or Missing Authorization weakness affecting the component's data handling paths.
Attack Vector
An attacker must possess valid credentials and local logon rights to the server that hosts Oracle Hyperion Infrastructure Technology. From that foothold, the attacker interacts with the Installation and Configuration component to perform unauthorized create, update, or delete operations against product data. No user interaction from another party is required, and attack complexity is low. Refer to the Oracle Security Alert August 2026 for authoritative technical guidance.
Detection Methods for CVE-2026-62577
Indicators of Compromise
- Unexpected modifications to Oracle Hyperion Infrastructure Technology configuration files or installation metadata.
- Data records in Hyperion-managed stores showing inserts, updates, or deletes without a corresponding change-management ticket.
- Local logon events for low-privileged accounts on Hyperion hosts followed by configuration component activity.
Detection Strategies
- Enable audit logging on the Hyperion Infrastructure Technology host and forward events to a centralized SIEM for correlation.
- Baseline the expected set of users who interact with the Installation and Configuration component and alert on deviations.
- Monitor file integrity on Hyperion installation directories and configuration stores to detect unauthorized changes.
Monitoring Recommendations
- Correlate local logon events with subsequent Hyperion administrative actions to identify anomalous sequences.
- Track privileged and low-privileged account usage on Hyperion servers and alert on rare or first-seen activity.
- Review Oracle Hyperion audit trails on a regular cadence and reconcile changes against approved change requests.
How to Mitigate CVE-2026-62577
Immediate Actions Required
- Apply the fixes referenced in the Oracle Security Alert August 2026 to affected Hyperion deployments.
- Inventory hosts running Oracle Hyperion Infrastructure Technology 11.2.25.0.000 and confirm patch status.
- Restrict local logon rights on Hyperion servers to the minimum required set of administrators.
Patch Information
Oracle addressed CVE-2026-62577 in its August 2026 Critical Patch Update / Security Alert cycle. Administrators should consult the Oracle Security Alert August 2026 for the specific patch identifiers and installation instructions applicable to Oracle Hyperion Infrastructure Technology 11.2.25.0.000.
Workarounds
- Enforce least privilege on the Hyperion host operating system to reduce the pool of accounts that can reach the vulnerable component.
- Require multi-person change control for modifications to Hyperion installation and configuration data.
- Isolate Hyperion Infrastructure Technology servers on segmented networks and gate access through jump hosts with session recording.
- Increase audit log retention and review frequency until patches are fully rolled out across the environment.
