# Drupal Webform: incorrect authorization lets users browse restricted pages

Drupal Webform versions up to 6.2.12 and 6.3.0 through 6.3.1 have an authorization flaw that lets a user reach pages they should not see by forced browsing. The sources give a CVSS score of 5.3 (medium) and no evidence of exploitation in the wild.

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

## How to check

- Run `composer show drupal/webform` on the Drupal site and compare the installed version with the affected range
- Check whether any Webform submission or results pages are reachable by users without the matching permission

## Fix

- Upgrade drupal/webform to `6.2.13` or later, or to a 6.3 release newer than `6.3.1` (the sources do not name the exact fixed version)
