Insecure deserialization In dompdf/dompdf
Description
Deserialization of Untrusted Data in dompdf/dompdf DomPDF before version 2.0.0 is vulnerable to PHAR (PHP Archive) deserialization due to a lack of checking on the protocol before passing it into the file_get_contents() function. An attacker who can upload files of any type to the server can pass in the phar:// protocol to unserialize the uploaded file and instantiate arbitrary PHP objects. This can lead to remote code execution, especially when DOMPdf is used with frameworks with documented POP chains like Laravel or vulnerable developer code.
Mitigation
Update Impact
