CVE-2026-45626 Details
Description
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 $() or backticks, and strconv.Quote only escapes Go string metacharacters, not shell substitution sequences. Any authenticated user with access to a browseable volume can execute arbitrary commands inside the helper container; command output is reflected back in the 500 error body.
A command injection vulnerability has been identified in Arcane versions through 1.18.1. The issue arises in the volume browsing feature, where the 'path' query parameter is not properly sanitized before being passed to a shell command inside an Arcane helper container. While the sanitizer blocks '../' traversal, it fails to remove Bourne-shell metacharacters such as '$()', backticks, and others. This allows any authenticated user with access to a browseable volume to execute arbitrary commands in the helper container. The output of these commands is then reflected in the response body as a server error.
