Name of the Vulnerable Software and Affected Versions Foxit PhantomPDF version 9.4.0.16811

Description This issue allows remote attackers to disclose sensitive information on vulnerable installations. It requires user interaction, such as visiting a malicious page or opening a malicious file. The flaw exists within the parsing of HTML files due to the lack of validating the existence of an object prior to performing operations on it. An attacker can leverage this, potentially in conjunction with other issues, to execute code in the context of the current process.
