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.

- CVE-2026-102435Critical
The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the _getObjAttr function in all versions up to, and including, 3.5.54. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This requires the PDF Generator add-on to be active and a Contact Form 7 form to be configured for PDF generation.

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.
