CVE-2026-45408— Dokku 命令注入漏洞

Dokku: OS Command Injection via App Name in Git Pre-Receive Hook

Dokku is a docker-powered PaaS. Prior to 0.38.2, the app name validation regex (^[a-z0-9][^/:_A-Z]*$) permits shell metacharacters. When an authenticated user pushes to a git remote with a crafted app name, the name is embedded unquoted into a bash pre-receive hook script via an unquoted heredoc (<<EOF instead of <<'EOF') in fn-git-create-hook() at plugins/git/internal-functions:378. On git push, bash interprets the semicolon as a command separator, executing arbitrary commands as the dokku user. This vulnerability is fixed in 0.38.2.

Dokku 命令注入漏洞

Dokku Dokku是Dokku团队的一个云平台部署工具。 Dokku 0.38.2之前版本存在命令注入漏洞，该漏洞源于应用名称验证正则表达式允许shell元字符，且应用名称在fn-git-create-hook()函数中被未引用嵌入到bash pre-receive hook脚本，可能导致经过身份验证的用户推送包含特制应用名称的git远程仓库时，bash将分号解释为命令分隔符，从而以dokku用户身份执行任意命令。
