CVE-2026-62502 Overview
CVE-2026-62502 is a high-severity vulnerability in the Oracle Hyperion Infrastructure Technology product, specifically within the Common Events component. The affected version is 11.2.25.0.000. An attacker with low privileges and network access via HTTP can exploit this flaw to compromise the application. Successful exploitation grants unauthorized creation, deletion, or modification of critical data, along with unauthorized read access to all data accessible by Oracle Hyperion Infrastructure Technology.
Critical Impact
Low-privileged network attackers can achieve unauthorized read, write, and delete access to critical Oracle Hyperion data over HTTP.

Technical Details for CVE-2026-62502
Vulnerability Analysis
The vulnerability resides in the Common Events component of Oracle Hyperion Infrastructure Technology. Oracle's advisory categorizes the flaw as easily exploitable over HTTP, requiring only low-privileged network access. The scope covers confidentiality and integrity impacts, with no direct availability impact. An authenticated attacker with minimal privileges can leverage the exposed HTTP interface to reach vulnerable functionality within Common Events. Because Oracle Hyperion is commonly deployed as an enterprise financial reporting and consolidation platform, exploitation exposes sensitive financial data and configuration state.
Root Cause
Oracle has not published detailed root-cause information beyond the component identification. The advisory indicates the weakness is reachable through standard HTTP request handling in the Common Events component. See the Oracle Security Alert for vendor-supplied details.
Attack Vector
Exploitation occurs remotely over HTTP. The attacker requires network reachability to the Hyperion Infrastructure Technology HTTP endpoint and a low-privilege account. No user interaction is required. Successful requests result in unauthorized access to and modification of data accessible by the Hyperion application. Refer to the Oracle Security Alert for exploitation prerequisites and mitigation guidance.
Detection Methods for CVE-2026-62502
Indicators of Compromise
- Unexpected HTTP requests to Oracle Hyperion Infrastructure Technology endpoints associated with the Common Events component.
- Unauthorized modification, creation, or deletion of Hyperion records or configuration data by low-privileged accounts.
- Anomalous authenticated sessions performing bulk data reads from Hyperion services.
Detection Strategies
- Enable HTTP access logging on Hyperion application servers and correlate authenticated user activity against expected role behavior.
- Baseline typical Common Events request patterns and alert on deviations in request volume, source IP, or user agent.
- Review Hyperion audit logs for data changes performed outside of scheduled business workflows.
Monitoring Recommendations
- Forward Hyperion application, web tier, and OS logs to a centralized SIEM for correlation with authentication telemetry.
- Monitor for privilege reuse where a single low-privileged account accesses data across multiple business domains.
- Track outbound data flows from Hyperion servers to identify potential exfiltration following unauthorized read access.
How to Mitigate CVE-2026-62502
Immediate Actions Required
- Apply the Oracle Critical Patch Update referenced in the Oracle Security Alert to all Hyperion Infrastructure Technology 11.2.25.0.000 deployments.
- Restrict network exposure of Hyperion HTTP endpoints to trusted management networks only.
- Audit low-privileged Hyperion accounts and remove or disable stale credentials.
Patch Information
Oracle addressed CVE-2026-62502 in its August 2026 Critical Patch Update. Administrators should review the Oracle Security Alert advisory and apply the vendor-supplied patch for Oracle Hyperion Infrastructure Technology 11.2.25.0.000.
Workarounds
- Place Hyperion Infrastructure Technology services behind a reverse proxy or web application firewall that enforces authentication and rate limiting.
- Segment Hyperion servers on a dedicated VLAN and restrict access via firewall rules to authorized application users and administrators.
- Enforce least-privilege role assignments and disable unused Hyperion accounts until patching completes.
