Description
Dokploy is a free, self-hostable Platform as a Service (PaaS). In 0.29.1 and earlier, a command injection vulnerability exists in the Docker file upload functionality. When an authenticated user uploads a file to a container, the destinationPath parameter is not properly sanitized and is directly interpolated into a shell command string. By including shell metacharacters such as ; or ", an attacker can escape the intended docker cp command and execute arbitrary OS commands on the Dokploy host.
