What is CVE-2026-45626?

Arcane, a tool for managing Docker containers, has a vulnerability that allows authenticated users to execute arbitrary commands within a helper container. Specifically, the API endpoint GET /environments/{id}/volumes/{volumeName}/browse permits a path query parameter, which, due to insufficient sanitization of Bourne-shell metacharacters, enables command injection. Although the path sanitization method prevents directory traversal through ../, it fails to adequately protect against other shell commands. As a result, any user with access to a browseable volume can exploit this vulnerability, with the command output reflected in the response body. This flaw poses significant risks to the integrity and confidentiality of systems utilizing Arcane.
