# Drupal Calculate Working Days: missing access check exposes pages to forced browsing

The Drupal Calculate Working Days module is missing an authorization check, so a visitor can reach pages or routes they should not see by requesting the URL directly. The sources do not say what data or actions those routes expose.

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

## How to check

- Check the installed version of the module with `drush pm:list --filter=calculate_working_days` or the Extend page in the Drupal admin
- Look in composer.lock for `drupal/calculate_working_days` and note the version

## Fix

- Update the Calculate Working Days module to a version later than `2.0.3`, per the Drupal.org project page (the sources do not name the fixed version)
