CVE-2026-62582 in Hyperion Calculation Manager
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Hyperion Calculation Manager product of Oracle Hyperion (component: 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 Calculation Manager. While the vulnerability is in Oracle Hyperion Calculation Manager, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Calculation Manager accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Calculation Manager accessible data. CVSS 3.1 Base Score 9.6 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N).

Analysis

The identified vulnerability resides within the Security component of Oracle Hyperion Calculation Manager, specifically affecting version 11.2.25.0.000 and potentially other supported releases in the suite. This flaw represents a critical security deficiency that allows for unauthorized manipulation or exfiltration of data stored by the application. The nature of this vulnerability is particularly concerning because it does not require high-level privileges to exploit, nor does it demand user interaction such as clicking on malicious links or opening specific files. Instead, an attacker with low-privileged access and network connectivity via HTTP can directly target the vulnerable component. This characteristic significantly lowers the barrier for entry, enabling individuals who might otherwise be restricted by basic authentication controls to escalate their influence over the system's data integrity and confidentiality.
The technical mechanism of this exploit likely involves a flaw in how the application processes security-related requests or manages session states within its web interface. By leveraging network access through HTTP, an attacker can send crafted payloads that bypass intended authorization checks or manipulate internal logic governing data permissions. The impact is severe because it affects both Confidentiality and Integrity aspects of the CIA triad, as reflected by a CVSS 3.1 Base Score of 9.6. Successful exploitation grants the adversary unauthorized capabilities to create, delete, or modify critical business data within Oracle Hyperion Calculation Manager. Furthermore, it may lead to complete access to all accessible data in the system, effectively compromising the confidentiality of sensitive financial models, planning assumptions, and calculation logic that are central to enterprise resource planning processes.
Beyond the immediate impact on Oracle Hyperion Calculation Manager, this vulnerability poses a significant risk due to scope change implications. Attacks targeting this component can significantly impact additional products within the broader Oracle Hyperion ecosystem or even downstream systems that rely on data integrity from these calculations. This interconnectedness means that compromising one module can serve as a pivot point for lateral movement across an organization's financial infrastructure. The ability to alter critical data introduces risks of financial misreporting, regulatory non-compliance, and operational disruption, while unauthorized access exposes proprietary business intelligence to competitors or malicious actors.
From a classification perspective, this vulnerability aligns with CWE-269 Improper Privilege Management and potentially CWE-862 Missing Authorization, as it allows low-privileged users to perform actions reserved for administrators or higher-level roles. In terms of the MITRE ATT&CK framework, this behavior corresponds to techniques such as T1078 Valid Accounts if the attacker uses legitimate but insufficient credentials to gain initial access, followed by T1496 Resource Hijacking or data manipulation tactics depending on the specific outcome. The lack of user interface interaction required for exploitation places it in categories associated with remote code execution vectors that do not rely on social engineering, making automated scanning and exploitation tools highly effective against this weakness.
Mitigation strategies must prioritize immediate patching to the latest available version provided by Oracle, which addresses the underlying security logic flaws within the Calculation Manager component. Organizations should also implement strict network segmentation to limit HTTP access to only authorized management subnets or virtual private networks where feasible. Enforcing multi-factor authentication for all administrative and user accounts adds a critical layer of defense against credential-based attacks. Additionally, deploying web application firewalls with rules tuned to detect anomalous request patterns associated with privilege escalation attempts can provide an additional shield during the transition period before full patching is completed. Regular audits of access controls and monitoring logs for unusual data modification events are essential to detect any potential exploitation in real-time.
