The module creates an endpoint on the site at /postfile/upload that accepts a POST request for uploading a single file into a specified file system (public, private, etc).
The module doesn't sufficiently protect against Cross Site Request Forgery
under allowing an attacker to trick a site user into uploading a file.
Install the latest version:
- If you use the POST File module for Drupal 10.3.x/11.x, upgrade to Post File 1.0.2
