Technical details

A missing authorization (CWE-862) vulnerability exists in the 'file_example' submodule of the Drupal Examples for Developers project. The 'Read from a file' feature fails to implement sufficient access controls, allowing for 'forceful browsing' where an attacker can request and view any file accessible to the PHP process. This vulnerability is particularly dangerous if developers have copied this example code into production environments. The issue is addressed in version 4.0.6 by removing the insecure submodule; users are advised to uninstall the submodule and upgrade.
