CVE-2026-44850— Portainer 安全漏洞

Portainer: Bind-mount restriction bypass via HostConfig.Mounts

Portainer Community Edition is a lightweight service delivery platform for containerized applications that can be used to manage Docker, Swarm, Kubernetes and ACI environments. From 2.33.0 to before 2.33.8, 2.39.2, and 2.41.0, Portainer offers an environment-level Disable bind mounts for non-administrators security setting that blocks regular users from binding host paths into containers they create through the Portainer-mediated Docker API. The check that enforces this setting only inspected the legacy HostConfig.Binds array on the container-create proxy and never looked at the equivalent HostConfig.Mounts array. Any authenticated user with rights to create containers on a Docker environment where the restriction is enabled could submit a bind-typed entry under HostConfig.Mounts and mount any host path into their container. This vulnerability is fixed in 2.33.8, 2.39.2, and 2.41.0.

Portainer 安全漏洞

Portainer是Portainer开源的一款用于管理Docker环境和Docker主机的轻量级用户管理界面。 Portainer 2.33.0版本至2.33.8之前版本、2.39.2之前版本和2.41.0之前版本存在安全漏洞，该漏洞源于禁用绑定挂载的安全设置仅检查HostConfig.Binds数组而未检查HostConfig.Mounts数组，允许具有容器创建权限的认证用户通过HostConfig.Mounts提交绑定类型条目挂载任意主机路径。
