DRUPAL-CONTRIB-2026-173
The advisory, in context
The Webform module allows site builders to create forms, collect submissions, and configure access to forms and submission data.
The module did not sufficiently restrict access to certain submission view modes. Under certain conditions, a user who can view a submission could access a more permissive view mode and see fields that would otherwise be restricted.
This vulnerability is mitigated by the fact that an attacker must already have access to view the affected submission.
