CVE-2026-70844 in Loans
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Loans product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Loans. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Loans accessible data as well as unauthorized update, insert or delete access to some of Oracle Loans accessible data. CVSS 3.1 Base Score 7.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N).

The identified vulnerability resides within the Internal Operations component of Oracle Loans, a critical module in the Oracle E-Business Suite ecosystem. This security flaw affects supported software versions ranging from 12.2.3 through 12.2.15. The nature of this defect allows for unauthorized access and manipulation of data by an attacker who possesses low-level privileges within the application environment. Unlike vulnerabilities that require high-privileged administrative accounts or complex social engineering, this flaw can be exploited by a user with minimal existing permissions, significantly lowering the barrier to entry for malicious actors targeting enterprise financial systems.
The technical mechanism enabling this compromise relies on network accessibility via the HTTP protocol. An attacker positioned within the same network segment as the Oracle E-Business Suite deployment can interact directly with the vulnerable endpoints without requiring any interaction from a legitimate user interface or visual prompt. This characteristic classifies the vulnerability as remotely exploitable and non-interactive, meaning that once an authenticated low-level account is obtained through other means such as credential theft or phishing, the attacker can immediately leverage this flaw to escalate their impact on the system's data integrity and confidentiality.
The operational consequences of a successful exploitation are severe, primarily impacting the confidentiality and integrity of sensitive financial records. The vulnerability permits unauthorized access to critical business data, which may include customer information, transaction histories, and proprietary financial models. Furthermore, it grants the ability to perform unauthorized updates, inserts, or deletions against specific datasets accessible by Oracle Loans. This capability allows an attacker not only to exfiltrate sensitive information but also to alter financial records, potentially leading to significant fiscal discrepancies, regulatory non-compliance, and reputational damage for the affected organization. The absence of availability impact suggests that while data is compromised, system uptime remains unaffected during such attacks.
From a classification perspective, this vulnerability aligns with Common Weakness Enumeration categories related to broken access control and insufficient authorization checks. Specifically, it reflects scenarios where an application fails to properly verify whether a user has the necessary permissions for specific actions or data retrieval operations before executing them. In terms of offensive security frameworks such as MITRE ATT&CK, this behavior is consistent with techniques involving unauthorized account access followed by data staging or modification. The CVSS 3.1 base score of 7.1 indicates a high severity level, driven largely by the high impact on confidentiality and moderate impact on integrity, while acknowledging that availability remains intact.
To mitigate this risk, organizations running affected versions must prioritize immediate patching to apply the latest security updates provided by Oracle for the Internal Operations component. It is essential to verify that all instances of Oracle E-Business Suite within the 12.2.x range are updated beyond version 12.2.3 up to at least 12.2.15 or later, depending on current patch availability. Additionally, implementing strict network segmentation can limit exposure by restricting HTTP access to these internal services from untrusted networks. Enhancing authentication mechanisms and monitoring for anomalous data modification patterns using intrusion detection systems will further reduce the window of opportunity for attackers attempting to exploit this specific weakness in low-privileged accounts.
