  "title": "ruby-rack: Rack is a modular Ruby web server interface",
  "description": "Rack is a modular Ruby web server interface. Prior to versions 2.2.22, 3.1.20, and 3.2.5, \u0060Rack::Directory\u0060 generates an HTML directory index where each file entry is rendered as a clickable link. If a file exists on disk whose basename starts with the \u0060javascript:\u0060 scheme (e.g. \u0060javascript:alert(1)\u0060), the generated index contains an anchor whose \u0060href\u0060 is exactly \u0060javascript:alert(1)\u0060. Clicking the entry executes JavaScript in the browser (demonstrated with \u0060alert(1)\u0060). Versions 2.2.22, 3.1.20, and 3.2.5 fix the issue.",
