CVE-2026-62499 Overview
CVE-2026-62499 is a medium-severity vulnerability in the Common Security component of Oracle Hyperion Infrastructure Technology. The affected version is 11.2.25.0.000. An unauthenticated attacker with network access via HTTP can exploit the flaw, but successful attacks require user interaction from a person other than the attacker. The vulnerability enables a scope change, meaning attacks may impact additional products beyond Oracle Hyperion Infrastructure Technology. Successful exploitation can result in unauthorized update, insert, or delete access to a subset of accessible data, along with unauthorized read access to a subset of that data.
Critical Impact
Unauthenticated network attackers can achieve unauthorized read and write access to Oracle Hyperion Infrastructure Technology data through crafted HTTP interactions that require victim participation.
Affected Products
- Oracle Hyperion Infrastructure Technology 11.2.25.0.000
- Component: Common Security
- Oracle Hyperion product family

Technical Details for CVE-2026-62499
Vulnerability Analysis
The vulnerability resides in the Common Security component of Oracle Hyperion Infrastructure Technology. Attackers reach the flaw over HTTP without prior authentication. The exploitation path requires human interaction from a user other than the attacker, which aligns with client-side attack patterns such as crafted links or malicious content rendered in an authenticated session. The scope change indicated by the CVSS vector means the impact extends beyond the vulnerable component into other Oracle products that trust Hyperion Infrastructure Technology.
Successful attacks yield partial confidentiality and integrity impact. Attackers can read a subset of accessible data and modify, insert, or delete records within reach of the affected component. Availability is not affected.
Root Cause
Oracle has not published detailed root-cause information for this issue in the referenced advisory. The combination of network attack vector, required user interaction, and scope change is consistent with a client-side flaw such as cross-site scripting or a request-forgery style weakness in the Common Security component. Consult the Oracle Security Alert for authoritative technical details.
Attack Vector
An unauthenticated attacker sends or hosts crafted HTTP content targeting the Common Security component. A legitimate user must interact with the attacker-supplied content, for example by clicking a link or loading a page, while their browser or client has an active session context. The interaction triggers the flaw, allowing the attacker to perform data reads and modifications within the victim's authorization boundary and to influence connected products through the scope change.
No verified proof-of-concept code has been published. See the Oracle Security Alert for vendor-provided technical context.
Detection Methods for CVE-2026-62499
Indicators of Compromise
- Unexpected HTTP requests to Oracle Hyperion Infrastructure Technology endpoints originating from user browsers rather than trusted clients.
- Unauthorized changes to Hyperion configuration or data records that do not correlate with legitimate administrator activity.
- Referrer headers pointing to external or untrusted domains on requests reaching the Common Security component.
Detection Strategies
- Monitor Hyperion access logs for anomalous HTTP methods or parameter patterns targeting authentication and security endpoints.
- Correlate user session activity with data modification events to identify actions performed via cross-site interactions.
- Baseline outbound requests from connected Oracle products to detect activity resulting from the scope-change condition.
Monitoring Recommendations
- Enable verbose HTTP request logging on Hyperion application servers and forward events to a central analytics platform.
- Alert on authenticated Hyperion actions originating from unexpected referrers or user-agent strings.
- Track privileged account activity in Hyperion and downstream Oracle products for out-of-hours or geographically anomalous events.
How to Mitigate CVE-2026-62499
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 access to Hyperion administrative interfaces to trusted management networks and VPN endpoints.
- Instruct Hyperion users to avoid following unsolicited links to Hyperion URLs and to log out of administrative sessions when not in use.
Patch Information
Oracle published fixes for this vulnerability as part of the Critical Patch Update referenced in the Oracle Security Alert. Administrators should identify the applicable patch for Oracle Hyperion Infrastructure Technology 11.2.25.0.000 and apply it following Oracle's deployment guidance.
Workarounds
- Place Hyperion Infrastructure Technology behind a web application firewall with rules that filter suspicious HTTP parameters and enforce strict referrer checks.
- Enforce SameSite cookie attributes and short session lifetimes for Hyperion administrative accounts to reduce the window for user-interaction-based attacks.
- Segment Hyperion from other Oracle products where feasible to limit the impact of scope-change exploitation until patching completes.
