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.  \nParsing 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.  \nThis is exploitable if attackers have control over the arguments being passed to `minimist`.\n\n\n## Recommendation\n\nUpgrade to versions 0.2.1, 1.2.3 or later.","state":0,"publishedAt":"2020-04-03T21:48:32+00:00","modifiedAt":"2026-03-13T22:11:31.390433+00:00","affected":[{"ecosystem":"npm","name":"minimist","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.2.1"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"minimist","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"1.0.0"},{"kind":"fixed","version":"1.2.3"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://nvd.nist.gov/vuln/detail/CVE-2020-7598","https://github.com/minimistjs/minimist/commit/10bd4cdf49d9686d48214be9d579a9cdfda37c68","https://github.com/minimistjs/minimist/commit/38a4d1caead72ef99e824bb420a2528eec03d9ab","https://github.com/minimistjs/minimist/commit/4cf1354839cb972e38496d35e12f806eea92c11f#diff-a1e0ee62c91705696ddb71aa30ad4f95","https://github.com/minimistjs/minimist/commit/63e7ed05aa4b1889ec2f3b196426db4500cbda94","https://github.com/substack/minimist","https://snyk.io/vuln/SNYK-JS-MINIMIST-559764","https://www.npmjs.com/advisories/1179","http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00024.html"],"sourceUrl":"https://github.com/advisories/GHSA-vh95-rmgr-6w4m","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-vh95-rmgr-6w4m","identifiers":["GHSA-vh95-rmgr-6w4m","CVE-2020-7598"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
