CVE-2026-3418
CriticalCVSS 9.1Summary
A vulnerability in the System REST API allows authenticated users with publisher privileges to upload files to arbitrary server-accessible locations due to insufficient validation of file type and destination. This could lead to code execution.
Risk Assessment
An authenticated publisher can upload malicious files to sensitive locations, potentially enabling remote code execution and full system compromise.
Recommendation
Implement strict file type validation and restrict destinations to allowed directories. Limit publisher privileges and monitor uploaded files.
Original NVD description (English source)
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.
