# Dockhand: read-only users can download any container file

Link for people: https://infrastack.ai/live/CVE-2026-126320 (this .md is for agents)

Dockhand before 1.0.55 lets users who only hold the containers:view permission download arbitrary files from containers, when they should need containers:exec. An attacker with such an account can retrieve secrets, keys and mounted credentials.

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

## How to check

- Check the Dockhand version in the running instance against the fixed release in the product ranges (unknown if the sources do not give it)
- Review which Enterprise RBAC roles hold containers:view and whether those accounts are needed

## Fix

- Dockhand: upgrade to `1.0.55` or later (per the advisory's 'before 1.0.55' range)

## Timeline

## Documents

- [advisory] Vendor advisory: github.com https://github.com/Finsys/dockhand/security/advisories/GHSA-r924-w2cm-9cjg
- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/dockhand-before-1.0.55-improper-authorization-via-container-file-download-endpoint

## From the sources

Dockhand before 1.0.55 contains an improper authorization vulnerability that lets users holding only containers:view download arbitrary container files instead of requiring containers:exec. Authenticated Enterprise RBAC users can request any path from the files/download endpoint, which reads through Docker's archive API, to retrieve secrets, keys, and mounted credentials.
