Rails is a web-application framework. Starting with version 5.2.0, there is
a possible sensitive session information leak in Active Storage. By
default, Active Storage sends a Set-Cookie header along with the user’s
session cookie when serving blobs. It also sets Cache-Control to public.
Certain proxies may cache the Set-Cookie, leading to an information leak.
The vulnerability is fixed in 7.0.8.1 and 6.1.7.7.
