Dockhand vulnerabilities

Dockhand before 1.0.36 contains an open redirect vulnerability in the OIDC initiation endpoint that allows unauthenticated remote attackers to redirect authenticated users to attacker-controlled sites by injecting an unvalidated redirect query parameter. Attackers can craft a malicious link to capture authorization codes via the Referer header and conduct credential phishing.

Dockhand before 1.0.45 contains an authentication bypass in which the global auth hook skips authentication for any path ending in a static-asset extension such as .js, including /api/* routes, and the user-mutation handlers fail open for unauthenticated callers. Unauthenticated remote attackers can send a PUT request to /api/users/<id>.js to reset the admin's or any user's password and take over the account.

Dockhand before 1.0.40 contains an authentication bypass vulnerability in its git webhook endpoints that allows unauthenticated remote attackers to trigger arbitrary stack redeployments by exploiting a null webhook secret guard condition. Attackers can enumerate sequential stack IDs and send unsigned webhook requests to force git clone and docker compose operations, enabling denial of service or, when combined with write access to the tracked git branch, container escape and full host compromise via attacker-controlled docker-compose.yml with privileged bind mounts.
