CVE-2026-121449

Dockhand before 1.0.54 contains a path traversal vulnerability that allows authenticated users to read, overwrite, and delete .env files outside the stacks root by double-encoding the stack name. Attackers can send %252e%252e sequences to /api/stacks/[name]/env/raw to disclose cross-environment secrets, write into protected directories, or poison deployment variables.

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 is a Docker management application. Prior to 1.0.34, the in-browser container terminal endpoint /api/containers/<id>/exec does not enforce authentication on the WebSocket upgrade request. When an unauthenticated attacker has network reach to Dockhand, knows a target container ID, and targets a container with an interactive shell, the attacker can open a raw WebSocket terminal session and execute commands inside the container.

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.

Dockhand before 1.0.46 contains an arbitrary file read vulnerability that allows non-admin users with stacks:edit permission to read files through the path parameter of /api/system/files/content. Attackers can supply absolute paths to read /etc/shadow, /etc/passwd, git .git/config credentials, and SSH keys from the Dockhand container.

Dockhand before 1.0.50 contains a privilege escalation vulnerability that allows users from another tenant to gain admin access because OIDC iss, aud, nonce and exp claims are not validated. Attackers with admin rights in another tenant of a shared provider like Microsoft Entra ID can recreate the mapped admin group and log in as Dockhand administrators.
