CVE-2026-66297— Livebook 命令注入漏洞

Unescaped deployment environment variables in generated setup commands

Improper Neutralization of Special Elements used in an OS Command (OS Command Injection) vulnerability in livebook-dev livebook allows command injection into generated deployment setup commands. LivebookWeb.Hub.Teams.DeploymentGroupAgentComponent.docker_instructions/2 and LivebookWeb.Hub.Teams.DeploymentGroupAgentComponent.fly_instructions/4 in lib/livebook_web/live/hub/teams/deployment_group_agent_component.ex interpolate deployment group environment variable values into the generated Docker and Fly.io setup commands without shell escaping. The values originate from the deployment group configuration and reach the sinks through Livebook.Hubs.Dockerfile.online_docker_info/3. Both sinks place the value inside a double-quoted shell word, so a value containing a command substitution such as $(...) or backticks is evaluated by the shell without any need to break out of the quoting, and a literal double quote terminates the quoted word and allows arbitrary further tokens. The generated command is displayed in the Livebook web interface with a copy button, so a user who copies it and runs it without reviewing it first executes the injected commands on their own machine, under their own account. An attacker requires privileges sufficient to set deployment group environment variables, while the resulting code execution occurs on the machine of whoever runs the generated command. The Kubernetes instructions are not affected, because they render the same values into a YAML manifest with escaping rather than into a shell command. This issue affects livebook: from 0.13.0 before 0.18.7 and from 0.19.0 before 0.19.9.

OS命令中使用的特殊元素转义处理不恰当(OS命令注入)

Livebook 命令注入漏洞

Livebook是Livebook组织开源的一款用于编写交互式协作代码笔记本的 Web 应用程序。 Livebook 0.13.0版本至0.18.7之前版本和0.19.0版本至0.19.9之前版本存在命令注入漏洞，该漏洞源于在生成Docker和Fly.io设置命令时未对部署组环境变量值进行shell转义，可能导致命令注入。
