All the vulnerabilities related to the version 0.3.0 of the package
Prototype Pollution in mpath
Versions of mpath before 0.5.1 are vulnerable to prototype pollution. Provided certain input mpath can add or modify properties of the Object prototype. These properties will be present on all objects.
Update to version 0.5.1 or later.
Type confusion in mpath
This affects the package mpath before 0.8.4. A type confusion vulnerability can lead to a bypass of CVE-2018-16490. In particular, the condition ignoreProperties.indexOf(parts[i]) !== -1 returns -1 if parts[i] is ['__proto__']. This is because the method that has been called if the input is an array is Array.prototype.indexOf() and not String.prototype.indexOf(). They behave differently depending on the type of the input.
