CVE-2026-62477 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 low privileged attacker with network access via HTTP to compromise Oracle Hyperion Infrastructure Technology. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Infrastructure Technology accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Infrastructure Technology accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/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 that lineage. This security flaw represents a significant risk to organizations relying on this enterprise performance management platform for critical business operations. The core issue stems from insufficient validation or access control mechanisms within the HTTP-based interface of the infrastructure layer, which serves as the backbone for various Hyperion applications including Financial Management, Planning and Budgeting, and Essbase. Because the vulnerability is located in a component responsible for handling authentication and authorization logic, its exploitation can bypass standard security boundaries that are designed to restrict user privileges based on their assigned roles within the application hierarchy.
From an operational perspective, this flaw allows attackers with low privileged accounts who have network access via HTTP to escalate their influence over the system significantly. The attack vector is classified as remote, meaning no physical or local console access is required, and it does not require any user interaction such as clicking a malicious link, which classifies it as non-interactive exploitation. This characteristic makes the vulnerability particularly dangerous in environments where internal network segmentation may be lax or where low-level service accounts have broader network connectivity than intended. The attacker can leverage this weakness to perform unauthorized actions that range from reading sensitive financial data and strategic plans to modifying critical configurations or deleting essential datasets, thereby disrupting business continuity and compromising data integrity.
The impact of a successful exploitation is severe, as indicated by the CVSS 3.1 base score of 8.1, which falls into the High severity category. The vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N) reveals that while Availability remains unaffected in this specific assessment, both Confidentiality and Integrity impacts are rated as High. This means an attacker can fully access all data accessible to the Hyperion infrastructure, including sensitive financial reports, employee records, and strategic forecasts, leading to substantial confidentiality breaches. Furthermore, the ability to modify or delete critical data introduces a high risk of integrity compromise, which could lead to erroneous decision-making by executives relying on corrupted metrics or complete loss of historical data if backups are not robustly maintained.
In terms of industry standard classifications, this vulnerability aligns with CWE-269 Improper Privilege Management and potentially CWE-862 Missing Authorization, as it allows a lower privileged user to perform actions reserved for higher privileges. It also maps closely to MITRE ATT&CK techniques such as T1078 Valid Accounts, where attackers use legitimate credentials that have been compromised or misconfigured to gain unauthorized access, and T1530 Data from Cloud Storage if the underlying data stores are accessed directly through this vulnerability. The lack of user interaction requirement places it in line with automated exploitation tools commonly used by threat actors targeting enterprise software vulnerabilities for rapid lateral movement within a network.
Mitigation strategies must focus on immediate patching and rigorous access control reviews. Oracle has likely released patches or updates addressing the Common Security component flaws; organizations should apply these updates to all instances of version 11.2.25.0.000 immediately. In addition to patching, it is critical to enforce strict network segmentation policies that limit HTTP access to Hyperion infrastructure components only from trusted management networks rather than general user subnets. Implementing Web Application Firewalls with rules specifically tuned for Oracle Hyperion traffic patterns can help detect and block exploitation attempts before they reach the application layer. Furthermore, organizations should conduct a thorough audit of all low-privileged accounts within the Hyperion environment to ensure that no unnecessary permissions are granted, adhering to the principle of least privilege. Regular vulnerability scanning focused on web-facing components and continuous monitoring for anomalous data access patterns will provide additional layers of defense against potential exploitation of this or similar vulnerabilities in the future.
