In js-yaml before 4.1.1 and 3.14.2, it's possible for an attacker to modify the prototype of the result of a parsed yaml document via prototype pollution (`__proto__`). All users who parse untrusted yaml documents may be impacted. The problem is patched in js-yaml 4.1.1 and 3.14.2. Users can protect against this kind of attack on the server by using `node --disable-proto=delete` or `deno` (in Deno, pollution protection is on by default)."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":1.4}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-1321"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:nodeca:js-yaml:*:*:*:*:*:node.js:*:*","versionEndExcluding":"3.14.2","matchCriteriaId":"8CAC7EC0-C471-4811-A77C-2DD5B47C7F46"},{"vulnerable":true,"criteria":"cpe:2.3:a:nodeca:js-yaml:*:*:*:*:*:node.js:*:*","versionStartIncluding":"4.0.0","versionEndExcluding":"4.1.1","matchCriteriaId":"B56B6076-0668-4DDC-8B01-C48019081B13"}]}]}],"references":[{"url":"https://github.com/nodeca/js-yaml/commit/383665ff4248ec2192d1274e934462bb30426879","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/nodeca/js-yaml/commit/5278870a17454fe8621dbd8c445c412529525266","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/nodeca/js-yaml/issues/730#issuecomment-3549635876","source":"security-advisories@github.com","tags":["Issue Tracking"]},{"url":"https://github.com/nodeca/js-yaml/security/advisories/GHSA-mh29-5h37-fv8m","source":"security-advisories@github.com","tags":["Vendor Advisory"]},{"url":"https://github.com/advisories/GHSA-mh29-5h37-fv8m","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
