Activerecord-session_store Timing Attack

description: |
The activerecord-session_store (aka Active Record Session Store) component
through 1.1.3 for Ruby on Rails does not use a constant-time approach when
delivering information about whether a guessed session ID is valid.
Consequently, remote attackers can leverage timing discrepancies to achieve a
correct guess in a relatively short amount of time. This is a related issue to
CVE-2019-16782.
