CVE-2021-23438 (GCVE-0-2021-23438)

Vulnerability from cvelistv5 – Published: 2021-09-01 18:20 – Updated: 2024-09-16 17:52
VLAI?
Summary
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.
Severity ?
