Merge Risk: 🟡 Moderate · up to The integrated deployment publishes the Console login on every host interface. A fresh install accepts the documented default administrator credentials, and that account can now stop, reconfigure and ban on the managed RustDesk servers. The node agent also runs as root with the host Docker socket, so a compromised agent or leaked agent token gives full control of the host. Bind the Console to localhost or require a password change before exposing it, and accept or reduce the agent's Docker trust boundary before merging. Security Architecture ReviewSecurity architecture risk: 🟠 High · up to Server management adds powerful controls to an existing login surface. Fresh installations still accept a known administrator password and publish an unencrypted endpoint, increasing the consequences of account or credential compromise to service disruption and access-policy changes.

Review comments at @agent/app.mjs:
- Around line 252-256: Keep the original deployment port in a separate
persistent label and use it as the fallback in `apply()` when no port override
exists; do not overwrite it on later port changes. Update `ready()` to compare
`/v1/config`’s effective port with the expected port, pass the replacement port
and rollback `oldPort` through the `docker.apply` readiness callbacks, and let a
mismatch fail readiness so rollback occurs.
Review comments at @agent/docker.mjs:
- Around line 235-259: Update the rollback catch block around beforeRollback in
the container replacement flow so each cleanup action runs independently, even
if a preceding action fails. Collect rollback-step failures without replacing
the original error, and preserve the final throw of that original error; apply
this to beforeRollback, replacement deletion, rename, network reconnects,
container restart, and ready.
Review comments at @docker-compose.integrated.yml:
- Line 30: Replace the agent’s raw Docker socket mount in
docker-compose.integrated.yml:30 with a socket-proxy service restricted to
container inspect, start, stop, restart, logs, rename, create, delete, and
network connect/disconnect operations, and configure DockerDriver to use that
proxy. In agent/Dockerfile:4, switch from root to the node user and ensure that
user can write to /data/management.

Remove the agent's unrestricted root-level Docker API access.
Two things combine here. The agent mounts the raw Docker socket, and the agent image runs as root. As a result, anyone who compromises the agent or holds NODE_AGENT_TOKEN has full control of the host. The service-name allow-list in DockerDriver limits what the agent code does. It does not limit what the socket allows. A :ro flag does not restrict Docker API calls.
docker-compose.integrated.yml#L30-L30: Replace the/var/run/docker.sockmount with a socket-proxy service. Allow only the operations the agent uses: container inspect, start, stop, restart, logs, rename, create and delete, plus network connect and disconnect. PointDockerDriverat the proxy.agent/Dockerfile#L4-L4: After the switch to the proxy, replaceUSER rootwithUSER node. Make sure/data/managementis writable by that user.

Independent assessment of this retained finding: agent process compromise implies Docker-host compromise (high confidence, 99%). Possession of NODE_AGENT_TOKEN alone does not expose arbitrary Docker requests: the API accepts fixed operations on configured/enrolled containers, and replacement payloads are derived from inspected containers rather than caller-supplied Docker payloads.
I am not adopting the suggested endpoint-only socket proxy as a security fix. A proxy that still permits unrestricted container creation can accept privileged/host-mount payloads from a compromised agent; changing USER does not remove Docker-daemon authority. The existing documentation makes this a trusted host-agent deployment boundary and identifies dedicated/rootless Docker hosts or an ownership/payload-aware broker as stronger alternatives. This is an accepted documented architectural risk, not a claim that host containment has been implemented. I am leaving this thread open for the maintainers' explicit disposition.

@hashbk, thanks for the clarification. My original finding overstated the authority granted by NODE_AGENT_TOKEN.
- Token possession is not arbitrary Docker API access. The agent exposes fixed operations on configured, enrolled containers.
- Agent process compromise remains a Docker-host compromise risk. An endpoint-only proxy that permits unrestricted container creation does not remove that risk.
- Changing
USER roottoUSER nodedoes not remove Docker-daemon authority. It is not host containment.
I retract the endpoint-only proxy recommendation as a sufficient security fix. The remaining concern is the accepted, documented trusted-host-agent boundary, not a demonstrated token-to-host escape.
The thread should remain open for the maintainers’ explicit disposition. No implementation change is requested in this reply.

Learning: In databk/rustdesk-console, the integrated Docker node agent is a trusted host component. Possession of NODE_AGENT_TOKEN grants access to fixed management operations on configured, enrolled containers, not arbitrary Docker requests. Replacement payloads derive from inspected containers. Agent process compromise can expose Docker-host authority. An endpoint-only socket proxy permitting unrestricted container creation, or changing the agent's operating-system user, does not establish host containment. Stronger isolation requires a dedicated or appropriately isolated rootless Docker host, or an ownership/payload-aware broker.

- Line 16: Update the Console port mapping in the Compose configuration so
remote clients cannot reach its HTTP login directly: expose it only to a local
TLS-terminating proxy, or enforce an equivalent TLS ingress for remote access.
Ensure credentials and bearer tokens are encrypted in transit.
- Line 16: Bind the integrated Compose service’s port 21114 to localhost rather
than all interfaces, so the Console with default administrator credentials is
not externally reachable before password rotation.

CI/workflow audit completed independently of the review suggestions.
No PR now adds a standalone workflow file. Existing release/nightly/CodeQL and main-branch MySQL migration checks remain intact. The retained jobs protect the feature's actual production artifacts and contracts; they are long-term PR/push checks. Removing the manual smoke scaffold means these checks do not establish full-stack deployment interoperability or provision/verify a TLS ingress. Latest heads passed all checks:
All compilation, application execution and tests ran in CI. Local work was limited to source review, formatting/lint and Git static checks. The new findings were assessed separately: HTTP/default-credential exposure and forwarded-IP mismatch (99% confidence, fixed), service/form context mismatch (95%, fixed), and recovered ban-form initialization (99%, fixed after verifying complete replacement semantics). Retained Docker-host authority is documented rather than represented as solved by an endpoint-only proxy. |

Console can now inspect and manage enrolled hbbs/hbbr services through a JWT/RBAC-protected backend proxy and a Docker node agent. The browser receives no node/server management credentials.
CI scope
Retain permanent backend/agent regressions and the agent image check in existing PR/push CI. Remove the temporary manual cross-repository workflow, its dedicated smoke script, and the added manual trigger on ordinary CI. Per-repository checks do not establish full-stack interoperability.
Validation
CI passed on 3146e36: backend/agent tests, lint, type checking, application build, MySQL migrations, both Docker checks and CodeQL. No local compilation, application execution or tests were performed.
Deployment limits
Enrollment is environment-based. The Docker-connected agent is a trusted host component; a compromised process can control its Docker host. An endpoint-only proxy permitting unrestricted container creation does not remove this boundary. Handled failures roll back, while interrupted-process replacements require operator recovery. Closing relay sessions does not close existing direct connections.
