WSO2 Micro Integrator Script Mediator Engine code injection

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in WSO2 Micro Integrator, API Manager, Enterprise Integrator, Universal Gateway, API Control Plane, Traffic Manager, Open Banking IAM, Open Banking AM, Identity Server as Key Manager, org.apache.synapse:synapse-core and org.apache.synapse:synapse-extensions. It has been rated as critical. Affected by this issue is some unknown processing of the component Script Mediator Engine. The manipulation with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. Impacted is confidentiality, integrity, and availability. CVE summarizes:

An arbitrary code execution vulnerability exists in multiple WSO2 products due to insufficient restrictions in the GraalJS and NashornJS Script Mediator engines. Authenticated users with elevated privileges can execute arbitrary code within the integration runtime environment. By default, access to these scripting engines is limited to administrators in WSO2 Micro Integrator and WSO2 Enterprise Integrator, while in WSO2 API Manager, access extends to both administrators and API creators. This may allow trusted-but-privileged users to perform unauthorized actions or compromise the execution environment.

The advisory is shared for download at security.docs.wso2.com. This vulnerability is handled as CVE-2025-11093 since 09/27/2025. The exploitation is known to be easy. Access to the local network is required for this attack to succeed. The exploitation needs additional levels of successful authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1059.
