summary 
json-jwt allows bypass of identity checks via a sign/encryption confusion attack
The json-jwt (aka JSON::JWT) gem 1.16.x before 1.16.6, 1.15.x before 1.15.3.1 for Ruby sometimes allows bypass of identity checks via a sign/encryption confusion attack. For example, JWE can sometimes be used to bypass JSON::JWT.decode.
