# Drupal Webform: privilege flaw lets users plant stored XSS

Drupal Webform module versions up to 6.2.12 and 6.3.0 through 6.3.1 have a privilege definition flaw that allows stored cross-site scripting. A user with the affected permission can store script in a form that runs in another user's browser.

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

## How to check

- Check the installed Webform version with `drush pm:list --filter=webform` or the Extend page in Drupal admin.
- Confirm whether the Webform module is enabled on the site.

## Fix

- Upgrade the Webform module to a version newer than `6.3.1` or `6.2.12`, as listed in the Drupal security advisory (unknown exact fixed version in sources).
