Dokploy: Command Injection in /docker-container-logs Endpoint

Dokploy is a free, self-hostable Platform as a Service (PaaS). In 0.26.6 and earlier, Dokploy contains a command injection vulnerability in the /docker-container-logs WebSocket endpoint. The tail and since parameters are not validated and are directly concatenated into shell commands, allowing authenticated users to execute arbitrary commands with root privileges.
