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.\n\n\n\nThis issue affects Field Collection for Drupal 7: version 7.x-1.0 up to and including 7.x-1.2.\n\n## Affected\n\n- `field_collection_for_drupal_7 >= 7.x-1.0 <= 7.x-1.2`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
