CVE-2023-0842: xml2js is vulnerable to prototype pollution

April 5, 2023 (updated April 12, 2023)

xml2js version 0.4.23 allows an external attacker to edit or add new properties to an object. This is possible because the application does not properly validate incoming JSON keys, thus allowing the proto property to be edited.
