Upstream source description

Foxel through 2.4.0 contains a missing authentication vulnerability that allows unauthenticated attackers to read files by requesting the /api/fs/stream and /api/fs/thumb endpoints. Attackers can supply a VFS mount prefix and relative path to retrieve full file contents or thumbnails across all mounts, bypassing PathRule permission grants.
