Vulnerability Details

This affects the package set-value before <2.0.1, >=3.0.0 <4.0.1. A type confusion vulnerability can lead to a bypass of CVE-2019-10747 when the user-provided keys used in the path parameter are arrays.
Mend Note: After conducting further research, Mend has determined that all versions of set-value up to version 4.0.0 are vulnerable to CVE-2021-23440.

This is an error from Mend:
I think Mend is right actually.

GHSA-4jqc-8m5r-9rpr says 2.0.1 is safe.
https://security.snyk.io/vuln/SNYK-JS-SETVALUE-1540541 says 2.0.1 is safe.

However, the discussion jonschlinkert/set-value#33 is a bit confusing.

set-value@2.0.1 was released in 2019 while this fix was a 2021 change. However, jonschlinkert/set-value@2.0.0...jonschlinkert:set-value:2.0.1 indicates some validation is happening. Empowered by the research from Snyk, I believe this is not an issue on 2.0.1.

[AMoo-Miki]

Checked Mend's own https://www.mend.io/vulnerability-database/CVE-2021-23440, this is a false positive.
