This module enables you to share users, content and configuration across a group of domains from a single Drupal installation. Its Domain Access submodule controls which domains a user may edit content on, and has an optional setting to grant user access per content type.

The module doesn't sufficiently check which domains a user is assigned to when the per-content-type grant setting is enabled.

This vulnerability is mitigated by the fact that the per-content-type grants setting must be enabled (it is off by default), and an attacker must have a role with the permission "Edit any content on assigned domains" or "Delete any content on assigned domains" together with a per-content-type permission such as "Article: Edit any content on assigned domains", and must be assigned to at least one domain.
