The actionpack ruby gem (a framework for handling and responding to web
requests in Rails) before 6.0.3.7, 6.1.3.2 suffers from a possible denial
of service vulnerability in the Mime type parser of Action Dispatch.
Carefully crafted Accept headers can cause the mime type parser in Action
Dispatch to do catastrophic backtracking in the regular expression engine.
