Doc Text:
A information disclosure flaw has been discovered in Drupal. The core system module handles downloads of private and temporary files. Contrib modules can define additional kinds of files (schemes) that may also be handled by the system module. In some cases, files may be served with the HTTP header Cache-Control: public when they should be uncacheable. This can lead to some users getting cached versions of files with information they should not be able to access. For example, files may be cached by Varnish or a CDN.
