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.
