Dockhand Plaintext Stack Secrets Exposure via Git-Stack Integration

Publication date: 2026-11-03

Last updated on: 2026-11-03

Assigner: VulnCheck

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.

Executive Summary

Dockhand versions 1.0.47 to 1.0.54 expose plaintext stack secrets. The deployStack() function attaches resolved secret values to its result as resolvedSecrets, which Git-stack routes return unfiltered. Attackers with a stack's webhook secret or stacks:start permission can trigger endpoints to retrieve stored secrets like those from 1Password or Vault.

Impact Analysis

Attackers could gain access to sensitive secrets such as passwords, API keys, or other credentials stored in external providers like 1Password or Vault. This could lead to unauthorized access to systems, data breaches, or further exploitation of the environment.

Compliance Impact

This vulnerability could lead to unauthorized access to personal or sensitive data, violating GDPR's data protection requirements or HIPAA's safeguards for protected health information. Organizations may face legal penalties, reputational damage, and loss of trust.

Mitigation Strategies

Upgrade Dockhand to version 1.0.54 or later to address the plaintext stack secrets exposure. Restrict access to endpoints triggering stack deployments and review permissions for users with stacks:start access.
