CVE-2026-87164 in Banking Branch
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Banking Branch product of Oracle Financial Services Applications (component: Reports). Supported versions that are affected are 14.5.0.0.0-14.9.0.0.0. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Banking Branch. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Banking Branch, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle Banking Branch. CVSS 3.1 Base Score 8.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H).

The identified vulnerability resides within the Reports component of Oracle Banking Branch, a critical module in the Oracle Financial Services Applications suite affecting versions 14.5.0.0.0 through 14.9.0.0. This security flaw is classified as difficult to exploit due to its high attack complexity and specific prerequisite conditions, yet it carries severe consequences for organizational integrity if successfully leveraged. The vulnerability allows a low-privileged attacker with network access via HTTP to compromise the application environment. While the initial point of entry is within Oracle Banking Branch, the nature of this flaw results in a scope change, meaning that successful exploitation can significantly impact additional products and services integrated into the broader financial infrastructure. This lateral movement capability amplifies the risk profile beyond the immediate component, potentially exposing sensitive data across multiple interconnected systems.
From a technical perspective, the vulnerability requires human interaction from a person other than the attacker to facilitate compromise. This characteristic aligns with social engineering vectors where an unsuspecting user may be tricked into performing actions that trigger the underlying code flaw. The requirement for low privileges indicates that the attacker does not need administrative rights or elevated system permissions to initiate the exploit, which is particularly dangerous in enterprise environments where privilege escalation paths are often numerous and difficult to monitor comprehensively. Once triggered, the vulnerability enables full takeover of Oracle Banking Branch, granting the adversary extensive control over application functions and data processing capabilities. This level of access allows for unauthorized modifications, data exfiltration, or disruption of services, directly impacting confidentiality, integrity, and availability as reflected in its high CVSS base score.
The operational impact of this vulnerability is substantial given the critical nature of banking operations. A successful attack can lead to complete system compromise, allowing attackers to manipulate financial records, steal customer information, or disrupt transaction processing. The scope change aspect implies that an attacker could potentially pivot from the Reports module into other parts of the Oracle Financial Services Applications ecosystem, leading to widespread data breaches and regulatory non-compliance. For financial institutions, such disruptions can result in significant reputational damage, legal liabilities, and direct financial losses. The high availability impact suggests that attackers may also deploy denial-of-service tactics or corrupt critical databases, rendering essential banking services unavailable during peak operational hours.
To mitigate this risk, organizations must prioritize immediate patching of the Oracle Banking Branch product to a version outside the affected range of 14.5.0.0.0-14.9.0.0. Since exploitation relies on human interaction and network access via HTTP, implementing strict input validation and sanitization mechanisms within the Reports component is essential. Security teams should enforce multi-factor authentication for all user accounts to reduce the likelihood of credential compromise facilitating initial access. Additionally, deploying web application firewalls can help detect and block malicious requests that attempt to exploit this vulnerability before they reach the application layer. Network segmentation strategies should be reviewed to limit lateral movement in case a breach occurs, ensuring that even if one component is compromised, the blast radius remains contained within isolated zones rather than spreading across the entire financial infrastructure.
This vulnerability maps to Common Weakness Enumeration categories such as CWE-79 for cross-site scripting or injection flaws depending on the specific code execution path, and potentially CWE-20 for improper input validation. In terms of MITRE ATT&CK framework tactics, this scenario aligns with Initial Access techniques involving user interaction, followed by Execution and Persistence if the attacker gains a foothold. The scope change aspect highlights the importance of understanding application dependencies and data flow between modules to prevent cascading failures. Continuous monitoring for anomalous HTTP traffic patterns related to report generation functions can aid in early detection. Regular security assessments and penetration testing focused on low-privilege user scenarios are recommended to identify similar weaknesses before they can be exploited by malicious actors targeting financial institutions.
