  "title": "ruby-carrierwave: CarrierWave is a solution for file uploads for Rails, Sinatra and other Ruby web frameworks",
  "description": "CarrierWave is a solution for file uploads for Rails, Sinatra and other Ruby web frameworks. CarrierWave has a Content-Type allowlist bypass vulnerability, possibly leading to XSS. The validation in \u0060allowlisted_content_type?\u0060 determines Content-Type permissions by performing a partial match. If the \u0060content_type\u0060 argument of \u0060allowlisted_content_type?\u0060 is passed a value crafted by the attacker, Content-Types not included in the \u0060content_type_allowlist\u0060 will be allowed. This issue has been patched in versions 2.2.5 and 3.0.5.",
