{"id":"CVE-2019-10747","aliases":["GHSA-4g88-fppr-53pp"],"url":"https://o3.security/vulnerability/CVE-2019-10747","summary":"Prototype Pollution in set-value","details":"Versions of `set-value` prior to 3.0.1 or 2.0.1 are vulnerable to Prototype Pollution. The `set` function fails to validate which Object properties it updates. This allows attackers to modify the prototype of Object, causing the addition or modification of an existing property on all objects.\n\n\n\n\n## Recommendation\n\nIf you are using `set-value` 3.x, upgrade to version 3.0.1 or later.\nIf you are using `set-value` 2.x, upgrade to version 2.0.1 or later.","published":"2019-08-23T17:15:13.403Z","modified":"2026-07-08T20:15:55.594532Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"npm","name":"set-value","fixedVersion":"2.0.1"},{"ecosystem":"npm","name":"set-value","fixedVersion":"3.0.1"}],"fix":{"url":"https://github.com/jonschlinkert/set-value/commit/95e9d9923f8a8b4a01da1ea138fcc39ec7b6b15f","label":"jonschlinkert/set-value@95e9d99"},"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/b46f35559c4a97cf74d2dd7fe5a48f8abf2ff37f879083920af9b292%40%3Cdev.drat.apache.org%3E"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3EJ36KV6MXQPUYTFCCTDY54E5Y7QP3AV/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/E3HNLQZQINMZK6GYB2UTKK4VU7WBV2OT/"},{"type":"EVIDENCE","url":"https://snyk.io/vuln/SNYK-JS-SETVALUE-450213"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-10747"},{"type":"WEB","url":"https://github.com/jonschlinkert/set-value/commit/95e9d9923f8a8b4a01da1ea138fcc39ec7b6b15f"},{"type":"WEB","url":"https://github.com/jonschlinkert/set-value/commit/cb12f14955dde6e61829d70d1851bfea6a3c31ad"},{"type":"WEB","url":"https://lists.apache.org/thread.html/b46f35559c4a97cf74d2dd7fe5a48f8abf2ff37f879083920af9b292@%3Cdev.drat.apache.org%3E"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3EJ36KV6MXQPUYTFCCTDY54E5Y7QP3AV"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/E3HNLQZQINMZK6GYB2UTKK4VU7WBV2OT"},{"type":"WEB","url":"https://www.npmjs.com/advisories/1012"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T20:15:55.594532Z"}}
