Vulnerability from github – Published: 2026-08-07 00:31 – Updated: 2026-08-07 00:31

Details

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.

Severity

9.1 (Critical)

Vulnerability from cvelistv5 – Published: 2026-08-06 17:32 – Updated: 2026-08-06 17:32

Title

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

Summary

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.

Severity

9.1 (Critical)
