CVE-2026-70685 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 unauthenticated attacker with logon to the infrastructure where Oracle Hyperion Calculation Manager executes 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 access to critical data or complete access to all Oracle Hyperion Calculation Manager accessible data as well as unauthorized update, insert or delete access to some of Oracle Hyperion Calculation Manager accessible data. CVSS 3.1 Base Score 7.9 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:L/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 an unauthenticated attacker to compromise the integrity and confidentiality of the application environment. The core technical issue stems from insufficient access control mechanisms or authentication bypass logic within the product's security architecture, which permits unauthorized entities to interact with sensitive system functions without proper credential validation. Although the vulnerability is localized to Oracle Hyperion Calculation Manager, its exploitation can lead to a significant scope change, impacting additional products that rely on shared infrastructure or data stores associated with the compromised instance. This lateral impact potential underscores the interconnected nature of enterprise application suites and highlights how a flaw in one module can destabilize broader organizational systems.
From an operational perspective, this vulnerability enables unauthenticated attackers who have network-level access to the infrastructure hosting Oracle Hyperion Calculation Manager to execute malicious actions. The attacker does not require prior authentication or user interaction, making the exploit straightforward and highly effective against misconfigured or exposed services. Successful exploitation results in unauthorized access to critical data stored within the system, including financial models, planning assumptions, and sensitive business intelligence metrics. Furthermore, the vulnerability grants the ability to perform unauthorized updates, inserts, or deletes on accessible data sets. This capability directly compromises data integrity, allowing an attacker to alter calculations, inject false data into reporting structures, or delete essential configuration files, thereby disrupting business operations and potentially causing significant financial or reputational damage depending on the organization's reliance on accurate hyperion-based planning processes.
The severity of this vulnerability is quantified by a CVSS 3.1 Base Score of 7.9, indicating a High level of risk. The vector string (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N) reveals that the attack requires Local network access with Low complexity and no privileges or user interaction required. Crucially, while Availability is not directly impacted in this specific scoring scenario, the Scope change to C indicates that the vulnerability affects resources beyond the vulnerable component itself. The High impact on Confidentiality reflects the potential for complete data exfiltration of sensitive financial information, while the Low impact on Integrity suggests that although write operations are possible, they may be restricted to certain datasets or require additional steps to achieve total system control. This profile aligns with common patterns in enterprise software where authentication bypasses lead to privilege escalation and unauthorized data manipulation rather than immediate denial-of-service conditions.
In terms of industry standard classifications, this vulnerability is best categorized under CWE-287: Improper Authentication, as it allows an actor to assume the identity of a legitimate user or access resources without valid credentials. Additionally, given the potential for scope change and impact on additional products, aspects of CWE-913: Improper Control of Dynamically-Managed Code Resources may be relevant if the vulnerability involves dynamic code execution or memory management flaws within the security module. From an offensive security perspective, this aligns with MITRE ATT&CK techniques related to Initial Access via Valid Accounts or Exploitation for Credential Access, depending on whether the attacker leverages existing infrastructure access to bypass authentication or exploits a direct flaw in the login mechanism itself. The lack of required user interaction and low attack complexity make it particularly dangerous in environments where internal network segmentation is weak or where management interfaces are exposed to broader corporate networks.
Mitigation strategies must focus immediately on isolating Oracle Hyperion Calculation Manager from untrusted networks and enforcing strict access controls. Organizations should ensure that the application server is not directly accessible via public-facing IP addresses and instead resides behind a secure web gateway or reverse proxy with robust authentication policies. Applying the latest security patches provided by Oracle for version 11.2.25.0.000 is essential, as these updates typically address specific logic flaws in the security module. Furthermore, implementing network segmentation to limit lateral movement can mitigate the scope change impact described in the vulnerability details. Security teams should also audit existing user accounts and permissions within Hyperion to ensure that only authorized personnel have access to critical data stores, reducing the blast radius if a breach occurs. Continuous monitoring for anomalous login attempts or unauthorized data modifications will aid in early detection of exploitation activities targeting this specific weakness.
