Official 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.

Technical Analysis

CVE-2026-45626 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
