  "details": "Arcane is an interface for managing Docker containers, images, networks, and volumes. In 1.18.1 and earlier, GET /environments/{id}/volumes/{volumeName}/browse accepts a path query parameter that is passed to a shell command (sh -c \"find … | while …\") inside an Arcane helper container. The path sanitiser blocks ../ traversal but does not strip Bourne-shell metacharacters such as $() or backticks, and strconv.Quote only escapes Go string metacharacters, not shell substitution sequences. Any authenticated user with access to a browseable volume can execute arbitrary commands inside the helper container; command output is reflected back in the 500 error body.",
