Possible Remote Code Execution Exploit in Rails Development Mode
There is a possible a possible remote code executing exploit in Rails when in
development mode. This vulnerability has been assigned the CVE identifier
CVE-2019-5420.
With some knowledge of a target application it is possible for an attacker to
guess the automatically generated development mode secret token. This secret
token can be used in combination with other Rails internals to escalate to a
remote code execution exploit.
All users running an affected release should either upgrade or use one of the
workarounds immediately.

Skip optimised #exist? query when #include? is called on a relation
with a having clause
Relations that have aliased select values AND a having clause that
references an aliased select value would generate an error when
#include? was called, due to an optimisation that would generate
call #exists? on the relation instead, which effectively alters
the select values of the query (and thus removes the aliased select
values), but leaves the having clause intact. Because the having
clause is then referencing an aliased column that is no longer
present in the simplified query, an ActiveRecord::InvalidStatement
error was raised.
An sample query affected by this problem:
Author.select('COUNT(*) as total_posts', 'authors.*')
.joins(:posts)
.group(:id)
Added Railtie#server hook called when Rails starts a server.
This is useful in case your application or a library needs to run
another process next to the Rails server. This is quite common in development
for instance to run the Webpack or the React server.
It can be used like this:
class MyRailtie < Rails::Railtie
server do
WebpackServer.run
end
end
