QID 981906

QID 981906: Nodejs (npm) Security Update for yargs-parser (GHSA-p9pc-299p-vxgp)

Affected versions of `yargs-parser` are vulnerable to prototype pollution. Arguments are not properly sanitized, allowing an attacker to modify the prototype of `Object`, causing the addition or modification of an existing property that will exist on all objects.
Parsing the argument `--foo.__proto__.bar baz'` adds a `bar` property with value `baz` to all objects. This is only exploitable if attackers have control over the arguments being passed to `yargs-parser`.



## Recommendation

Upgrade to versions 13.1.2, 15.0.1, 18.1.1 or later.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
