Specifically, the script lacks proper sanitization of\nthe hash data before utilizing it to establish the top-level window's\nlocation. This oversight permits an attacker to inject malicious\nJavaScript payloads through carefully crafted URLs.\n\nSnippet from \"frames.erb\":\n(v0.9.34)\n```erb\n<script type=\"text/javascript\">\n  var match = unescape(window.location.hash).match(/^#!(.+)/);\n  var name = match ? match[1] : '<%= url_for_main %>';\n  name = name.replace(/^(\\w+):\\/\\//, '').replace(/^\\/\\//, '');\n  window.top.location = name;\n</script>\n```\n\n(v0.9.35)\n```erb\n<script type=\"text/javascript\">\n  var match = decodeURIComponent(window.location.hash).match(/^#!(.+)/);\n  var name = match ? match[1] : '<%= url_for_main %>';\n  name = name.replace(/^((\\w*):)?[\\/\\\\]*/gm, '').trim();\n  window.top.location.replace(name)\n</script>\n```\n\n### PoC (Proof of Concept)\n\nTo exploit this vulnerability:\n1. Gain access to the generated Yard Doc.\n2. Locate and access the \"frames.html\" file.\n3. Construct a URL containing the malicious payload in the hash\n   segment, for instance: `#!javascript:xss` for v0.9.34, and\n   `#:javascript:xss` for v0.9.35\n\n### Impact\n\nThis XSS vulnerability presents a substantial threat by enabling\nan attacker to execute arbitrary JavaScript code within the user's\nsession context. Potential ramifications include session hijacking,\ntheft of sensitive data, unauthorized access to user accounts, and\ndefacement of websites. Any user visiting the compromised page is\nsusceptible to exploitation. It is critical to promptly address\nthis vulnerability to mitigate potential harm to users and preserve\nthe application's integrity.\n","cvss_v2":null,"cvss_v3":5.4,"cve":"2024-27285","osvdb":null,"ghsa":"8mq4-9jjh-9xrc","unaffected_versions":[],"patched_versions":[">= 0.9.36"],"criticality":"medium"}}]}
