# Drupal Advanced Search: missing access check lets users browse restricted pages

The Drupal Advanced Search module is missing an authorization check, so a user can reach pages they should not see by requesting their address directly. The sources describe this as forceful browsing and do not say which data is exposed.

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

## How to check

- Check the installed Advanced Search module version with `drush pm:list --filter=advanced_search` or in the Drupal admin under Extend.
- unknown for anything else, the sources do not list the affected routes or settings.

## Fix

- Upgrade the Advanced Search module to a version newer than `2.4.5`, per the Drupal.org security advisory (the sources do not name the fixed version).
