## Description

Files is a module for managing files inside spaces and user profiles. Prior to versions 0.16.11 and 0.17.2, insufficient authorization checks allow non-member users to create new folders, up- and download files as a ZIP archive in public spaces. Private spaces are not affected. This issue has been patched in versions 0.16.11 and 0.17.2.

## What to do

- Check your stack: if you ship or depend on humhub cfiles, upgrade to a fixed version (0.16.11, 0.17.2) per the references below.
