Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

arcane是Arcane开源的一个Docker管理软件。 Arcane 1.19.4之前版本存在路径遍历漏洞，该漏洞源于ProjectService.GetProjectFileContent在路径遍历验证前返回Docker Compose包含指令内容，可能导致经过身份验证的用户创建包含恶意include路径的项目并读取任意文件。

Vulnerability Title
Arcane: Authenticated Arbitrary Host File Read via Docker Compose Include Directives in Arcane
Source: CVE Program / CVE List V5
Vulnerability Description
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.
