CVE-2026-70931 in Workflow
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle Workflow product of Oracle E-Business Suite (component: Workflow Notification Mailer). 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 Workflow. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Workflow accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Workflow. CVSS 3.1 Base Score 8.1 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H).

The identified vulnerability resides within the Workflow Notification Mailer component of Oracle E-Business Suite, specifically affecting versions ranging from 12.2.3 to 12.2.15. This critical security flaw allows for remote code execution or significant system compromise by a low-privileged attacker who possesses network access via HTTP. The presence of this vulnerability in the notification mailer highlights a potential weakness in how the application processes incoming requests, potentially involving improper input validation or logic errors that can be leveraged to bypass existing authentication and authorization controls. Given that Oracle E-Business Suite is often deployed as a central enterprise resource planning platform containing sensitive financial, human resources, and operational data, any compromise of its workflow subsystem poses a severe risk to the overall integrity and availability of the organization's digital infrastructure.
From a technical perspective, the vulnerability enables an attacker with low privileges to execute actions that should be restricted to higher-level administrators or system processes. The ability to create, delete, or modify critical data indicates a failure in access control mechanisms, allowing unauthorized manipulation of workflow states, notifications, and associated metadata. This aligns closely with CWE-269, which describes Improper Privilege Management, as well as CWE-74, which relates to Injection flaws if the attack vector involves injecting malicious content through HTTP parameters or headers. The attacker does not require user interaction (UI:N), making this a straightforward remote exploitation scenario that can be automated and scaled across vulnerable instances without detection by typical security monitoring tools that do not inspect deep application-layer logic for privilege escalation patterns.
The operational impact of successfully exploiting this vulnerability is substantial, characterized primarily by high integrity loss and complete availability disruption. The unauthorized creation or modification of data can lead to severe business process failures, financial discrepancies, or the introduction of backdoors within the workflow engine itself. Furthermore, the capability to cause a hang or frequently repeatable crash constitutes a Denial of Service condition, effectively rendering the Oracle Workflow service unavailable to legitimate users. This availability impact disrupts critical business operations that rely on automated approvals, notifications, and task assignments. The CVSS 3.1 base score of 8.1 reflects this severity, emphasizing that while confidentiality is not directly impacted in all scenarios, the potential for data tampering and system unavailability makes it a high-risk issue requiring immediate attention.
In terms of threat modeling, this vulnerability maps to MITRE ATT&CK techniques such as T1078 Valid Accounts if the low-privileged attacker uses legitimate credentials obtained through other means, or potentially T1496 Resource Hijacking if the denial-of-service aspect is leveraged for disruptive purposes. The attack vector being network-accessible via HTTP suggests that it could be exploited over the internet if the service is exposed without adequate web application firewall protections or strict access control lists restricting source IP addresses to trusted internal networks only.
To mitigate this risk, organizations running affected versions of Oracle E-Business Suite must apply the latest security patches provided by Oracle as soon as possible. Until patching can be performed, it is advisable to restrict network access to the Workflow Notification Mailer component strictly to authorized application servers and administrative workstations using firewall rules or reverse proxy configurations. Additionally, implementing robust web application firewalls with specific rule sets designed to detect anomalous HTTP requests targeting workflow endpoints can provide a layer of defense against exploitation attempts. Regular auditing of user privileges within Oracle E-Business Suite is also recommended to ensure that low-privileged accounts do not possess unnecessary access rights to the workflow subsystem, thereby reducing the attack surface available to potential adversaries.
