Prototype Pollution in minimist

Open Source Vulnerabilities GHSA-vh95-rmgr-6w4m

Affected versions of `minimist` 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 `--__proto__.y=Polluted` adds a `y` property with value `Polluted` to all objects. The argument `--__proto__=Polluted` raises and uncaught error and crashes the application. This is exploitable if attackers have control over the arguments being passed to `minimist`. ## Recommendation Upgrade to versions 0.2.1, 1.2.3 or later.

Open Source Vulnerabilities CVE-2020-7598
