# Drupal Webform Submissions Delete: missing access check lets users delete submissions

The Webform Submissions Delete module for Drupal lacks an authorization check, so a user can reach its delete function without permission. An attacker can remove webform submissions they should not be able to touch.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed version of the Webform Submissions Delete module with `drush pm:list --filter=webform_submissions_delete` or `composer show drupal/webform_submissions_delete`
- Confirm whether the module is enabled on the site with `drush pm:list --status=enabled`

## Fix

- Update the Webform Submissions Delete module to a release later than `1.2.0`; the sources do not name the fixed version
- Until patched, disable the module if the bulk delete feature is not needed
