CVE-2019-10744 is a prototype-pollution vulnerability in Lodash versions earlier than 4.17.12. The vulnerable defaultsDeep function can be supplied with a crafted constructor payload that adds or modifies properties on Object.prototype. Applications that pass attacker-controlled objects through this function can inherit attacker-defined properties in other application objects.
