CVE-2021-23438
Type confusion in mpath
5.6
MEDIUM
CVSS 3.1
EPSS 0.52%
描述
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.
