User Private Files vulnerability

What happened

The User Private Files WordPress plugin before 2.2.0 does not properly protect its stored private files on multisite installations, where the rewrite rule it relies on to route file requests through its access check is never reached, allowing unauthenticated users to retrieve other users' private files directly.

Affected versions

User Private Files: before 2.2.0 (semver) Fixed: See vendor advisory.
