CVE-2026-23944— arcane 访问控制错误漏洞

Arcane allows unauthenticated proxy access to remote environments

Arcane is an interface for managing Docker containers, images, networks, and volumes. Prior to version 1.13.2, unauthenticated requests could be proxied to remote environment agents, allowing access to remote environment resources without authentication. The environment proxy middleware handled `/api/environments/{id}/...` requests for remote environments before authentication was enforced. When the environment ID was not local, the middleware proxied the request and attached the manager-held agent token, even if the caller was unauthenticated. This enabled unauthenticated access to remote environment operations (e.g., listing containers, streaming logs, or other agent endpoints). An unauthenticated attacker could access and manipulate remote environment resources via the proxy, potentially leading to data exposure, unauthorized changes, or service disruption. Version 1.13.2 patches the vulnerability.

关键功能的认证机制缺失

arcane 访问控制错误漏洞

arcane是Arcane开源的一个Docker管理软件。 arcane 1.13.2之前版本存在访问控制错误漏洞，该漏洞源于环境代理中间件在强制执行身份验证之前处理对远程环境的请求，可能导致未经验证的请求被代理到远程环境代理，从而未经身份验证即可访问远程环境资源。
