CVE-2026-3418

Arbitrary File Upload via System REST API in Multiple WSO2 Products Allows Remote Code Execution PUBLISHED

Description (CNA)

The System REST API accepts user-supplied file uploads without enforcing sufficient validation on the file type or destination, allowing files to be written to arbitrary server-accessible locations. Exploitation requires authenticated administrative access with publisher privileges. Successful exploitation permits an authenticated publisher to upload files to server-accessible locations. Depending on the deployment environment and how uploaded files are handled, this could lead to the execution of uploaded content, potentially resulting in remote code execution.
