Summary
Field Collection for Drupal 7 from 7.x-1.0 through 7.x-1.2 has an improper authorization flaw (CWE-285). The access check for field collection items grants edit and delete access to any user with the "edit field collections" permission without checking access to the parent entity. A user with that permission can edit or delete field collection items on an entity they cannot edit, bypassing node access restrictions.

Description from the CNA
Improper Authorization vulnerability in Drupal Field Collection for Drupal 7 allows a user with the "edit field collections" permission to bypass access control on the parent (host) entity. The access check for field collection items (field_collection_item_access()) granted edit and delete access to any user holding the "edit field collections" permission without verifying the user's access to the host entity. As a result, a user with "edit field collections" but without edit/update access to the host entity (for example a node they cannot edit) could edit or delete field collection items attached to that entity, bypassing the intended entity/node access restrictions. The fix requires access to the parent entity in addition to the field collection permission. This issue affects Field Collection for Drupal 7: version 7.x-1.0 up to and including 7.x-1.2.
