CVE-2026-70743 in Hyperion Financial Reporting
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Hyperion Financial Reporting product of Oracle Hyperion (component: Server). The supported version that is affected is 11.2.25.0.000. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Oracle Hyperion Financial Reporting. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Hyperion Financial Reporting accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Hyperion Financial Reporting. CVSS 3.1 Base Score 8.2 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:L).

Analysis

The identified vulnerability resides within the server component of Oracle Hyperion Financial Reporting, specifically affecting version 11.2.25.0.000 and potentially other supported releases in that lineage. This security flaw is characterized by its high exploitability due to the absence of any required authentication prerequisites. An attacker can leverage this weakness solely through network access via the HTTPS protocol, which means they do not need valid credentials or user interaction to initiate an attack vector against the target system. The presence of a secure transport layer does not mitigate the underlying logic flaw that allows unauthorized entities to interact with sensitive server functions directly over encrypted channels.
From a technical perspective, this vulnerability enables unauthenticated remote attackers to compromise the integrity and availability of the Oracle Hyperion Financial Reporting application. The core issue likely stems from insufficient access control mechanisms or improper validation of incoming requests within the web service layer handling financial reporting data. Because the attack vector is network-based with low complexity, automated exploitation tools can be deployed effectively against exposed instances. The lack of authentication requirements significantly lowers the barrier to entry for malicious actors, allowing them to bypass standard security perimeters that rely on identity verification as a primary defense mechanism.
The operational impact of this vulnerability is severe, primarily impacting confidentiality and availability while leaving integrity relatively unaffected according to the provided CVSS metrics. Successful exploitation grants an attacker unauthorized access to critical financial data stored within the system. This includes sensitive reports, fiscal summaries, and proprietary business intelligence that are central to organizational decision-making processes. The exposure of such information can lead to significant competitive disadvantage, regulatory non-compliance, and reputational damage. Furthermore, the vulnerability allows for a partial denial of service condition, where an attacker can disrupt normal operations by exhausting server resources or causing application instability through malformed requests, thereby hindering legitimate users from accessing essential financial reporting tools when needed most.
In terms of industry standard classifications, this vulnerability aligns with CWE-287 Improper Authentication and CWE-352 Cross-Site Request Forgery if the mechanism involves state-changing actions without proper verification, though it is primarily an access control failure. It also maps to MITRE ATT&CK technique T1078 Valid Accounts or potentially T1190 Exploit Public-Facing Application depending on whether existing credentials are bypassed or entirely circumvented through logic flaws. The high confidentiality impact corresponds to CWE-200 Information Exposure, while the availability impact relates to CWE-400 Uncontrolled Resource Consumption if the denial of service is resource-based.
Mitigation strategies must prioritize immediate patching and access control hardening. Oracle should be consulted for the latest security patches that address this specific flaw in version 11.2.25.0.000. In the interim, network segmentation policies should restrict HTTPS access to the Hyperion Financial Reporting server strictly to authorized IP ranges or virtual private networks rather than exposing it directly to the public internet. Implementing a Web Application Firewall with rules designed to detect and block anomalous request patterns associated with unauthenticated exploitation attempts can provide an additional layer of defense. Additionally, enforcing strict input validation on all endpoints serving financial data will help prevent malformed requests that trigger denial-of-service conditions. Regular security audits focusing on authentication mechanisms for public-facing applications are essential to ensure no similar gaps exist in related modules within the Oracle Hyperion suite.
