Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Dokku 是一个基于 Docker 的平台即服务（PaaS）解决方案。在 Dokku 0.38.25 之前的版本中，拥有应用级别 Dokku 访问权限且具备远程 SSH 权限以执行 命令的用户，可以通过 插件存储任意字符串。这些字符串随后会被拼接到 环境变量中，并在构建（build）、部署（deploy）或运行（run）操作期间由 Bash 的 命令进行处理。由于存储在值中的 Shell 命令替换符会在主机上被解释执行，攻击者可以利用此漏洞以 Dokku 操作系统用户的权限执行任意命令。该问题已在 0.38.25

Vulnerability Title
Dokku: Host Command Execution via eval of Unsanitized Docker Options in DOCKER_ARGS
Source: CVE Program / CVE List V5
Vulnerability Description
Dokku is a docker-powered platform as a service. In Dokku versions before 0.38.25, a user with app-level Dokku access and remote SSH access to execute docker-options commands can store arbitrary strings through the docker-options plugin, and those strings are later concatenated into DOCKER_ARGS and processed by Bash eval during build, deploy, or run operations. Shell command substitutions in the stored values are interpreted on the host, allowing arbitrary command execution with the privileges of the dokku operating-system user. This issue is fixed in version 0.38.25.
