CVE-2026-62529 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. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Hyperion Calculation Manager accessible data. CVSS 3.1 Base Score 3.5 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:N).

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 that lineage. This flaw represents a significant security deficiency in how the application handles user authentication and authorization processes over web-based interfaces. The core technical issue involves an improper validation mechanism within the HTTP request handling logic, which allows for unauthorized manipulation of data integrity controls. While the vulnerability is classified as easily exploitable due to low attack complexity, it requires specific conditions regarding privilege levels and human interaction to be successfully leveraged by a threat actor.
From a technical perspective, this flaw aligns with CWE-20 Improper Input Validation or potentially CWE-918 Server-Side Request Forgery depending on the exact vector of exploitation within the calculation engine's security layer. The vulnerability permits an attacker who possesses low-level privileges and has network access via HTTP to bypass intended restrictions. This is not a remote code execution flaw but rather an authorization bypass that targets data integrity. An adversary can exploit this weakness by crafting specific HTTP requests that manipulate internal state or database operations, leading to unauthorized updates, inserts, or deletes of accessible data within the Oracle Hyperion environment.
The operational impact of this vulnerability centers on the compromise of data integrity, which is reflected in a CVSS 3.1 Base Score of 3.5 with an Integrity impact rating of Low. Although the score appears modest, the implications for financial planning and analysis systems like Oracle Hyperion are severe because these platforms often contain sensitive corporate financial models, budgets, and forecasts. Unauthorized modification or deletion of this data can lead to significant business disruption, inaccurate reporting, and potential regulatory compliance failures. The requirement for human interaction suggests that social engineering tactics may be employed, such as tricking a privileged user into clicking a malicious link or submitting a crafted form within the application interface, thereby triggering the vulnerability.
In terms of threat modeling, this behavior is consistent with ATT&CK technique T1078 Valid Accounts if the attacker uses legitimate but low-privileged credentials to perform unauthorized actions, or potentially T1564 Hidden Files and Directories if the exploitation involves obscuring changes made to data structures. The attack vector being Network (AV:N) indicates that no physical access is required, making it a remote threat accessible over corporate networks or the internet depending on deployment configuration. The Low Privileges (PR:L) requirement means that even users with minimal initial access can escalate their impact by exploiting this flaw to alter critical data without needing administrative rights.
Mitigation strategies must focus on both immediate remediation and long-term architectural improvements. Oracle should be consulted for the latest security patches or updates that address this specific vulnerability in version 11.2.25.0.000. Organizations running affected versions are advised to apply these patches immediately upon availability. In addition to patching, implementing strict input validation on all HTTP endpoints related to calculation management is essential. Security teams should also enforce the principle of least privilege more rigorously, ensuring that low-privileged users have minimal access to sensitive data structures. Network segmentation can further limit exposure by restricting HTTP access to the Hyperion Calculation Manager interface only from trusted internal subnets or through a secure web application firewall with robust rule sets designed to detect and block anomalous request patterns indicative of this exploitation attempt.
