Project: File (Field) Paths [1]
Date: 2022-December-14
Security risk: *Moderately critical* 12∕25
AC:Basic/A:None/CI:Some/II:None/E:Theoretical/TD:Default [2]
Vulnerability: Access bypass

Description: 
The File (Field) Paths module extends the default functionality of Drupal's
core File module, by adding the ability to use entity-based tokens in
destination paths and file names.

The module's default configuration could temporarily expose private files to
anonymous visitors.

*Important note:*  to fix the problem, database updates must be run in
addition to updating the module.

It's possible to make a configuration change to mitigate this problem in the
admin UI at /admin/config/media/file-system/filefield-paths - the temp file
location should use either the temporary:// or private:// stream wrapper if
uploaded files should not be exposed publicly.

This vulnerability is mitigated by the fact that an attacker must be able to
guess the temporary path used for file upload.

Solution: 
Install the latest version:

  * If you use the File (Field) Paths module for Drupal 7.x, upgrade to File
    (Field) Paths 7.x-1.2 [3]
