Summary

The Field Collection module for Drupal 7 (versions 7.x-1.0 through 7.x-1.2) has an improper authorization flaw. field_collection_item_access() grants edit and delete access to any user with the 'edit field collections' permission without verifying access to the host entity.

Risk Assessment

A user without edit access to the host entity can modify or delete attached field collection items, bypassing intended content access restrictions.

Recommendation

Update the Field Collection module to a version containing the fix. Until patched, restrict the 'edit field collections' permission to trusted roles.

Original NVD description (English source)

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.
