CVE-2026-87307 in JD Edwards EnterpriseOne Tools
Summary
by MITRE • 10/21/2026
Vulnerability in the JD Edwards EnterpriseOne Tools product of Oracle JD Edwards (component: Interoperability SEC). Supported versions that are affected are 9.2.0.0-9.2.26.5. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise JD Edwards EnterpriseOne Tools. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all JD Edwards EnterpriseOne Tools accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of JD Edwards EnterpriseOne Tools. CVSS 3.1 Base Score 7.1 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L).

The identified vulnerability resides within the Interoperability SEC component of Oracle JD Edwards EnterpriseOne Tools, specifically affecting supported versions ranging from 9.2.0.0 through 9.2.26.5. This security flaw is classified as a high-severity issue with a CVSS v3.1 base score of 7.1, indicating significant risk to organizational data integrity and system availability. The vulnerability stems from an implementation error within the interoperability layer that handles secure communications or authentication mechanisms, allowing for unauthorized access when specific conditions are met. This component is critical for integrating JD Edwards with external systems and services, making its compromise particularly dangerous as it can serve as a pivot point for further lateral movement within the enterprise network.
The technical nature of this flaw allows an attacker to exploit the vulnerability through standard HTTP protocols without requiring user interaction or complex pre-conditions beyond basic network connectivity. The attack vector is classified as Network (AV:N) with Low Complexity (AC:L), meaning that no specialized tools or sophisticated techniques are required to trigger the exploitation. Crucially, the privilege requirement for this attack is listed as Low (PR:L), which implies that an attacker does not need administrative privileges on the target system but rather only needs a standard user account within the JD Edwards environment. This significantly lowers the barrier to entry for malicious actors who may have already gained initial foothold access through phishing or other social engineering tactics, allowing them to escalate their impact by targeting this specific interoperability module.
Successful exploitation of this vulnerability results in two primary adverse outcomes: unauthorized access to critical data and a partial denial of service against the JD Edwards EnterpriseOne Tools platform. The confidentiality impact is rated as High (C:H), meaning that sensitive business information stored within or accessible through the enterprise one environment can be exfiltrated by the attacker. This could include financial records, customer personal identifiable information, supply chain details, or proprietary operational data. Simultaneously, the availability impact is rated as Low to Medium depending on interpretation of partial DOS (A:L), suggesting that an attacker can disrupt normal operations by causing service degradation or temporary unavailability of specific tools within the suite. This dual-impact profile aligns with CWE Category 287 Improper Authentication and potentially CWE 400 Uncontrolled Resource Consumption if the denial of service is achieved through resource exhaustion techniques, though the primary concern remains data breach via improper access control enforcement in the interoperability layer.
From a threat intelligence perspective, this vulnerability maps to MITRE ATT&CK technique T1078 Valid Accounts, as it relies on low-privileged credentials to gain unauthorized access. It also relates to T1530 Data from Cloud Storage if the compromised data is exfiltrated via cloud-based interoperability channels, or T1046 Network Service Discovery if used for mapping internal assets. The ability to cause a partial denial of service may also correlate with T1499 Endpoint Denial of Service, although the scope here is limited to specific tools rather than the entire infrastructure. Organizations must recognize that even low-privileged accounts can pose severe risks when interacting with high-value components like interoperability services, which often have broader permissions or access to backend databases and APIs than standard user interfaces suggest.
Mitigation strategies should prioritize immediate patching of all affected JD Edwards EnterpriseOne Tools instances to version 9.2.26.5 or later where the vulnerability is resolved. In environments where patching cannot be performed immediately, network segmentation policies must be reviewed to ensure that systems hosting vulnerable components are not directly accessible from untrusted networks via HTTP. Implementing strict access control lists (ACLs) on firewalls and web application firewalls can help restrict traffic to only authorized IP ranges for the interoperability endpoints. Additionally, enabling enhanced logging and monitoring for authentication failures or unusual data retrieval patterns within the Interoperability SEC component is recommended to detect potential exploitation attempts in real-time. Security teams should also audit user permissions across JD Edwards environments to ensure that low-privileged accounts do not have unnecessary access to sensitive interoperability functions, adhering to the principle of least privilege to reduce the attack surface available to compromised credentials.
