Fortinet Discovers Portainer Path Traversal Vulnerability
Fortinet's FortiGuard Labs has discovered a path traversal vulnerability in Portainer.

Portainer is meant to be as simple to deploy as it is to use. It consists of a single container that can run on any Docker engine (can be deployed as Linux container or a Windows native container, supports other platforms too). Portainer allows you to manage all your Docker resources (containers, images, volumes, networks and more).
