Last updated on: 2026-11-13

Assigner: VulnCheck

Description
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.

Executive Summary

Dockhand before version 1.0.55 has an improper authorization vulnerability. Authenticated users with only containers:view permission can download arbitrary files from containers via the files/download endpoint. This bypasses the intended containers:exec requirement, allowing access to sensitive data like secrets, keys, and credentials through Docker's archive API.

Detection Guidance

Check Dockhand version with: docker exec <container> dockhand --version. If version is before 1.0.55, the system is vulnerable. Inspect API logs for unauthorized GET requests to /api/containers/{id}/files/download with containers:view but not containers:exec permissions.

Impact Analysis

This vulnerability allows unauthorized users to download sensitive files from containers, including secrets, keys, and credentials. Attackers with containers:view but not containers:exec permissions can exploit this to access confidential data, potentially leading to data breaches or further system compromise.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. Organizations using affected versions may face compliance violations, legal penalties, and reputational damage due to potential data exposure.

Mitigation Strategies

Upgrade Dockhand to version 1.0.55 or later. If immediate upgrade is not possible, restrict containers:view permissions in Enterprise RBAC to prevent unauthorized file downloads.
