CVE-2013-4562
The omniauth-facebook gem 1.4.1 before 1.5.0 does not properly store the session parameter, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks via the state parameter.
Does this matter?
Lower severity and a low EPSS score (1.17%). Track it; it rarely justifies an emergency change on its own.
