Arbitrary File Read in html-pdf

  • Disclosed: 11.10.2019
  • Updated: 11.10.2026 10:22

All versions of html-pdf are vulnerable to Arbitrary File Read. The package fails to sanitize the HTML input, allowing attackers to exfiltrate server files by supplying malicious HTML code. XHR requests in the HTML code are executed by the server. Input with an XHR request such as request.open("GET","file:///etc/passwd") will result in a PDF document with the contents of /etc/passwd.
