Official description

Dockhand from 1.0.47 before 1.0.54 exposes plaintext stack secrets because deployStack() attaches resolved secret values to its result as resolvedSecrets, which Git-stack routes return unfiltered. Holders of a stack's webhook secret or users with stacks:start permission can trigger the Git stack webhook, manual deploy, or create-and-deploy endpoints to receive stored and external-provider secrets such as 1Password or Vault values.
