Cloudron's auth wall does not replace app-level roles

Cloudron can place an authentication layer in front of installed applications and restrict access to selected users or groups. That is a useful control for self-hosted services that lack their own identity integration. It is not the same as granting the right role inside each application.

What the measurements show

On 2026-11-07 UTC, page-one count-only ZoomEye probes with sub_type=all returned zero for app="Cloudron" and 33,782 for title="Cloudron". The title result is large enough to require semantic filtering. It can include documentation, customer sites, marketing pages and app portals that share the product name.

Cloudron's documentation states that only authentication is handled by the app access layer. The installed application still decides what an authenticated user can read or change. A group allowed through the front door may contain users who should not be application administrators.

Review the two access decisions

For each app, record the Cloudron access mode: all users, selected users and groups, or a public setting where supported. List the group owners and the process for adding a member. Then inspect the application's own administrator, editor and viewer roles.

Cloudron API tokens also need scope review. The API can set app access restrictions with a bearer token, so a write-capable token can change who reaches an application. Store it as a secret, assign an owner and expire it after the automation or integration is retired.

Group access should be tested from an account that is not a member. Confirm that the auth wall blocks access to the application and to direct asset paths that might bypass the landing page. Then test an allowed non-administrator inside the app to verify that the auth wall does not accidentally promote the user.

Keep an ownership record

The inventory should connect the public hostname, Cloudron app, access group, application role and responsible team. After staff changes, remove stale group memberships and API tokens. After an application update, repeat the role test because the app's internal model may have changed.

The public title count is a candidate list, not a list of exposed accounts. The security decision comes from the access mode and the application role behind it.
