python3.9 is vulnerable to XML External Entity (XXE). This vulnerability exists due to a flaw in the way the plistlib module parses certain XML plist files. An attacker can exploit this vulnerability by sending a specially crafted plist file that references an external entity, which could allow the attacker to read arbitrary files on the system or execute arbitrary code.
