# Download Monitor WordPress plugin serves files outside uploads on multisite

On WordPress multisite, a subsite administrator can approve arbitrary filesystem locations that Download Monitor then serves to anyone. That exposes readable files outside the uploads directory, including other subsites' files, to unauthenticated visitors.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Confirm the site runs WordPress multisite and has Download Monitor installed; single-site installs are unaffected.
- Check the installed plugin version against `5.3.5`.
- Review the approved file locations in the Download Monitor settings for paths outside the uploads directory (exact location not stated in the sources).

## Fix

- Update Download Monitor to `5.3.5` or later.
- Until updated, restrict who holds subsite administrator rights on the multisite network.

## From the sources

The Download Monitor WordPress plugin before 5.3.5 does not correctly restrict management of the list of filesystem locations it may serve files from to network administrators on multisite, allowing a subsite administrator who is not trusted at the network level to approve arbitrary locations and have the Download Monitor WordPress plugin before 5.3.5 serve readable files from outside the uploads directory, including files belonging to other subsites, to unauthenticated visitors; single-site installations are unaffected.
