CVE-2026-62499 in Hyperion Infrastructure Technology
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Hyperion Infrastructure Technology product of Oracle Hyperion (component: Common Security). The supported version that is affected is 11.2.25.0.000. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Hyperion Infrastructure Technology. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Hyperion Infrastructure Technology, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Hyperion Infrastructure Technology accessible data as well as unauthorized read access to a subset of Oracle Hyperion Infrastructure Technology accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

The identified vulnerability resides within the Common Security component of Oracle Hyperion Infrastructure Technology, specifically affecting version 11.2.25.0.000 and potentially other supported releases in the suite. This flaw represents a critical weakness in how the application handles authentication and access control mechanisms for its HTTP-based interfaces. The core technical issue involves an insufficient validation or authorization check that permits unauthenticated actors to interact with sensitive backend functions. While the vulnerability is technically located within the infrastructure layer, it serves as a gateway that can lead to broader compromises across dependent Oracle Hyperion products due to shared data stores and integrated security contexts. This scope expansion means that exploiting this single entry point can destabilize or compromise multiple applications within the enterprise analytics ecosystem, rather than being isolated to the infrastructure service itself.
From an operational perspective, the exploitability of this vulnerability is characterized by a low attack complexity but requires human interaction for successful execution. The attacker must have network access via HTTP and typically needs to trick a legitimate user into performing an action that triggers the vulnerable code path, such as clicking a malicious link or interacting with a crafted web request while authenticated in another session if cross-site scripting vectors are involved, although the primary descriptor emphasizes unauthenticated access leading to data manipulation. The requirement for human interaction suggests social engineering tactics may be necessary to initiate the exploit chain, yet once triggered, the consequences are severe. The vulnerability allows an attacker to gain unauthorized read access to a subset of accessible data and, more critically, enables unauthorized updates, inserts, or deletes against other data within Oracle Hyperion Infrastructure Technology. This dual impact on both confidentiality and integrity distinguishes it from simple information disclosure flaws, as it actively alters the state of the system's data repository.
The security implications are significant given that Oracle Hyperion is often used for critical financial reporting, budgeting, and performance management in large enterprises. Unauthorized modification or deletion of configuration settings, user preferences, or underlying metadata can lead to inaccurate business intelligence outputs, regulatory non-compliance, and operational disruption. The unauthorized read access exposes sensitive corporate data, including potentially confidential financial figures or strategic plans stored within the Hyperion environment. Because the vulnerability allows for write operations without proper authentication checks at the specific component level, it effectively bypasses standard security controls that rely on session validation for these particular endpoints. This represents a classic case of broken access control where the server fails to verify that the user is authorized to perform the requested action before executing database commands or file system changes.
In terms of industry classification standards, this vulnerability aligns with CWE-287 Improper Authentication and CWE-918 Server-Side Request Forgery (SSRF) if the attack involves manipulating server-side requests, though it most closely maps to CWE-862 Missing Authorization when considering the data manipulation aspect. The exploitation technique falls under MITRE ATT&CK tactic T1078 Valid Accounts or potentially T1534 Internal Spearphishing if human interaction is strictly required via phishing links that trigger backend API calls. The CVSS 3.1 base score of 6.1 reflects a medium severity rating, driven by the network vector and low complexity but tempered slightly by the requirement for user interaction and the limited scope of availability impact which remains at zero. However, in practice, the ability to alter data often leads to denial-of-service conditions indirectly through corruption or system instability, even if not explicitly scored as an availability loss.
Mitigation strategies must focus on immediate isolation and patching. Organizations should apply the latest security patches provided by Oracle for Hyperion Infrastructure Technology immediately after testing them in a non-production environment to ensure compatibility with existing integrations. Until patches are applied, network-level controls such as Web Application Firewalls (WAF) can be configured to block requests targeting the specific vulnerable endpoints or parameters associated with the Common Security component. Access control lists should restrict HTTP access to these infrastructure services to only known internal IP ranges if possible, preventing external unauthenticated actors from reaching the attack surface. Additionally, monitoring for anomalous database write operations originating from web application sessions can help detect exploitation attempts in real-time. Regular audits of user permissions and session management policies are also recommended to ensure that no excessive privileges exist within the Hyperion environment that could be leveraged if this specific vector is bypassed or mitigated by other means.
