CVE-2026-44454— Coder vulnerable to workspace auto-creation via crafted URL parameters without user consent

Coder vulnerable to workspace auto-creation via crafted URL parameters without user consent

Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.7 and 2.30.2, the `dotfiles` registry module passed unsanitized user input to shell commands, allowing arbitrary code execution inside a provisioned workspace. Any user who supplied a crafted `dotfiles_uri` value (for example, one containing shell command substitution such as `$(...)`) could achieve command execution in their own workspace. The Create Workspace page's `mode=auto` deep links amplified this into a one-click attack: an attacker could craft a URL that prefilled `param.dotfiles_uri` and silently provisioned a workspace with the attacker-controlled value, with no explicit user confirmation. In versions 2.29.7 and 2.30.2, input validation was added to the dotfiles module to reject URIs and usernames containing special characters, and the unsafe `eval`/`sh -c` usage was removed. This eliminated the command injection at its source.

Coder 命令注入漏洞

Coder是Coder组织开源的一个可以在公共或私有云基础设施中设置开发环境的应用程序。 Coder 2.29.7之前版本和2.30.2之前版本存在命令注入漏洞，该漏洞源于`dotfiles` registry模块将未经清理的用户输入传递给shell命令，可能导致恶意用户通过特制`dotfiles_uri`值在预置工作空间内执行任意代码。
