CVE-2026-62460 Overview
CVE-2026-62460 is an information disclosure 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. A low-privileged attacker with network access via HTTP can exploit this issue to gain unauthorized read access to a subset of Oracle Hyperion Calculation Manager accessible data. The vulnerability involves a scope change, meaning successful exploitation may impact additional products beyond Calculation Manager itself. Oracle documented the issue in the Oracle Security Alert.
Critical Impact
Low-privileged network attackers can read confidential data from Oracle Hyperion Calculation Manager and potentially affect connected Oracle Hyperion components through a scope-change condition.
Affected Products
- Oracle Hyperion Calculation Manager 11.2.25.0.000
- Oracle Hyperion (Security component)
- Downstream Oracle Hyperion products reachable through the scope-changed attack path

Technical Details for CVE-2026-62460
Vulnerability Analysis
The issue resides in the Security component of Oracle Hyperion Calculation Manager. An authenticated user with minimal privileges can send crafted HTTP requests that return data the user is not authorized to view. The vulnerability produces a scope change, so the compromised trust boundary differs from the vulnerable component. This condition typically indicates that the Calculation Manager acts on behalf of another component, exposing data owned by adjacent Oracle Hyperion services. Impact is limited to confidentiality; integrity and availability of the system remain intact. Oracle classifies exploitation as easily achievable over a network without user interaction.
Root Cause
Oracle has not released detailed technical root-cause information beyond identifying the flaw within the Security component of Calculation Manager. The behavior aligns with a broken access control or information exposure weakness, where authorization checks fail to enforce data boundaries across trust zones.
Attack Vector
The attack vector is network-based over HTTP. An attacker authenticates with low privileges to a Calculation Manager endpoint and issues requests that traverse into resources belonging to other Hyperion components. No user interaction is required, and the attack complexity is low. No public proof-of-concept exploit is currently available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
No verified exploitation code is publicly available. Refer to the Oracle Security Alert for vendor-specific technical detail.
Detection Methods for CVE-2026-62460
Indicators of Compromise
- Unexpected HTTP requests to Calculation Manager endpoints from accounts holding only baseline Hyperion roles
- Access log entries showing successful reads of resources outside a user's assigned Hyperion scope
- Elevated volumes of API responses returning object metadata to low-privilege sessions
Detection Strategies
- Baseline typical Calculation Manager URL patterns and alert on deviations from authenticated low-privilege sessions
- Correlate authentication events with resource-access events to identify horizontal data access
- Review Oracle Hyperion audit logs for successful reads immediately following a session established by a non-administrative account
Monitoring Recommendations
- Enable verbose HTTP access logging on the Calculation Manager web tier and forward logs to a centralized analytics platform
- Monitor for scope-change indicators such as cross-component references in a single HTTP transaction
- Track EPSS movement for CVE-2026-62460 (currently 0.295%, percentile 22.122) to detect shifting exploitation likelihood
How to Mitigate CVE-2026-62460
Immediate Actions Required
- Apply the fixes released in the Oracle Critical Patch Update referenced in the Oracle Security Alert
- Inventory all Oracle Hyperion Calculation Manager instances running version 11.2.25.0.000
- Restrict network access to Calculation Manager HTTP endpoints to trusted management networks
- Review low-privilege Hyperion accounts and remove any that are unused
Patch Information
Oracle addressed CVE-2026-62460 in the August 2026 Oracle Security Alert. Administrators should install the vendor-supplied patch for Oracle Hyperion Calculation Manager 11.2.25.0.000 following Oracle's documented upgrade procedure. See the Oracle Security Alert for the corresponding patch identifiers and staged rollout guidance.
Workarounds
- Place Calculation Manager behind a reverse proxy or web application firewall that enforces strict authorization on sensitive HTTP paths
- Segment Hyperion components on isolated network zones to reduce blast radius from any scope-change exploitation
- Temporarily disable non-essential low-privilege accounts until the vendor patch is applied
