# Dockhand: path traversal lets authenticated users read stored credentials

Link for people: https://infrastack.ai/live/CVE-2026-126321 (this .md is for agents)

Dockhand before 1.0.55 lets a user with stacks:edit permission bypass its file-browser path check using symlinks and '..' sequences. An attacker can read /proc/self/environ, the SQLite database and the encryption key, exposing stored credentials.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Dockhand affected range not listed fixed no fixed version listed

## How to check

- Check the installed Dockhand version and compare it with `1.0.55`
- Look for the Dockhand container image tag or release in your deployment config

## Fix

- Dockhand: upgrade to `1.0.55` or later

## From the sources

Dockhand before 1.0.55 contains a path traversal vulnerability that allows authenticated users with stacks:edit to bypass the file-browser path guard by combining symlinks with '..' sequences. Attackers can read /proc/self/environ, the SQLite database, and the encryption key via /api/system/files/content, or move them using the stack relocate endpoint, exposing stored credentials.
