CVE-2026-82999 in Service Delivery Platform
Summary
by MITRE • 09/16/2026
Vulnerability in the Service Delivery Platform product of Oracle Fusion Middleware (component: Messaging Enabler). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Service Delivery Platform. While the vulnerability is in Service Delivery Platform, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Service Delivery Platform. CVSS 3.1 Base Score 9.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).

The identified vulnerability resides within the Messaging Enabler component of Oracle Fusion Middleware’s Service Delivery Platform, affecting versions 12.2.1.4.0 and 14.1.2.0.0. This critical security flaw allows for remote code execution or system compromise by an attacker who possesses low-level privileges but has network access via the HTTP protocol. The severity of this issue is underscored by a CVSS v3.1 base score of 9.9, indicating a Critical level risk that impacts confidentiality, integrity, and availability equally. The attack vector requires no user interaction and involves low complexity, making it highly exploitable in environments where such services are exposed to the network without adequate segmentation or authentication controls.
From a technical perspective, this vulnerability represents a significant escalation of privilege scenario where an authenticated but unprivileged attacker can leverage flaws within the messaging infrastructure to gain full control over the Service Delivery Platform instance. The operational impact extends beyond the immediate component due to scope changes inherent in how Oracle Fusion Middleware products interact. A compromise of the Service Delivery Platform can lead to lateral movement and cascading failures across additional integrated products, effectively undermining the security posture of the entire middleware environment. This aligns with CWE-269 Improper Privilege Management, as the vulnerability allows a low-privileged entity to perform actions reserved for higher-level administrators or system processes.
The exploitation of this flaw enables an attacker to achieve complete takeover of the affected Service Delivery Platform. This level of access permits the modification of application logic, theft of sensitive data processed through the messaging enabler, and disruption of critical business operations dependent on these services. The high availability impact suggests that successful attacks could render essential communication channels inoperative, leading to significant operational downtime. In terms of threat modeling, this vulnerability facilitates actions consistent with MITRE ATT&CK techniques such as T1078 Valid Accounts for initial access via low-privileged credentials and potentially T1059 Command and Scripting Interpreter if the compromise leads to arbitrary code execution on the underlying host system.
Mitigation strategies must prioritize immediate patching of all affected Oracle Fusion Middleware versions to 12.2.1.4.0 or later, specifically targeting patches that address this specific messaging enabler flaw. In environments where patching is not immediately feasible, network segmentation should be enforced to restrict HTTP access to the Service Delivery Platform strictly from trusted internal subnets. Implementing robust authentication mechanisms and ensuring that only high-privileged accounts have administrative access can reduce the attack surface. Additionally, deploying web application firewalls with rules designed to detect anomalous messaging protocol behavior may provide an additional layer of defense against exploitation attempts while permanent remediation is applied.
