CVE-2026-47179

Περιγραφή

Arcane is an interface for managing Docker containers, images, networks, and volumes. Prior to 1.19.4, ProjectService.GetProjectFileContent returns the contents of any Docker Compose include directive declared in a project-s compose file before any path-traversal validation runs. Because ProjectService.CreateProject writes attacker-supplied compose content to disk without validating include paths, an authenticated user can create a project whose compose file declares include: [-../../../../etc/passwd-], then read the include via the project file API. The result is arbitrary read of any file readable by the Arcane backend process, including /app/data/arcane.db (the SQLite database containing every user-s password hash and API key), enabling escalation to admin and, via Arcane-s Docker control plane, RCE on the host. This vulnerability is fixed in 1.19.4.
