[3.7] drupal7: Files uploaded by anonymous users into a private file system can be accessed by other anonymous users (CVE-2017-6922)
Private files that have been uploaded by an anonymous user but not
permanently attached to content on the site should only be visible to
the anonymous user that
uploaded them, rather than all anonymous users. Drupal core did not
previously provide this protection, allowing an access bypass
vulnerability to occur. This issue
is mitigated by the fact that in order to be affected, the site must
allow anonymous users to upload files into a private file system.
Affected versions:
Drupal core 7.x versions prior to 7.56
Fixed In Version:
drupal 7.56
