Detailsinfo

A vulnerability was found in Dokploy up to 0.29.12 and classified as critical. This issue affects the function writeTraefikConfigRemote of the file packages/server/src/utils/traefik/application.ts of the component Traefik Configuration. The manipulation with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, writeTraefikConfigRemote in packages/server/src/utils/traefik/application.ts serializes user-controlled Traefik configuration with yaml.stringify and interpolates the resulting yamlStr into an echo command executed through execAsyncRemote. Single quotes in redirect regex and replacement fields, basic authentication usernames, domain host values, or middleware configuration can terminate the shell quoting and execute arbitrary commands on managed remote servers with the configured SSH user's privileges. This vulnerability is caused by an incomplete fix for CVE-2026-45630. This issue is fixed in version 0.29.13.
