An arbitrary file read exists in Galaxy 22.01 and Galaxy 22.05 due to the switch to Gunicorn, which can be used to read any file accessible to the user under which Galaxy is running.
Impact
This vulnerability affects Galaxy 22.01 and higher, after the switch to gunicorn, which serve static contents directly. Additionally, the vulnerability is mitigated when using Nginx or Apache to serve /static/* contents, instead of Galaxy's internal middleware.
