{"id":"GHSA-cwx2-736x-mf6w","summary":"Prototype pollution in object-path","details":"### Impact\nA prototype pollution vulnerability has been found in `object-path` \u003c= 0.11.4 affecting the `set()` method. The vulnerability is limited to the `includeInheritedProps` mode (if version \u003e= 0.11.0 is used), which has to be explicitly enabled by creating a new instance of `object-path` and setting the option `includeInheritedProps: true`, or by using the default `withInheritedProps` instance. The default operating mode is not affected by the vulnerability if version \u003e= 0.11.0 is used. Any usage of `set()` in versions \u003c 0.11.0 is vulnerable.\n \n### Patches\nUpgrade to version \u003e= 0.11.5\n\n### Workarounds\nDon't use the `includeInheritedProps: true` options or the `withInheritedProps` instance if using a version \u003e= 0.11.0.\n\n### References\n[Read more about the prototype pollution vulnerability](https://codeburst.io/what-is-prototype-pollution-49482fc4b638)\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [object-path](https://github.com/mariocasciaro/object-path)","aliases":["CVE-2020-15256"],"modified":"2026-07-08T06:00:47.441827685Z","published":"2020-10-19T20:55:55Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2020-10-19T20:52:39Z","nvd_published_at":"2020-10-19T22:15:00Z","cwe_ids":["CWE-20","CWE-471"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/mariocasciaro/object-path/security/advisories/GHSA-cwx2-736x-mf6w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15256"},{"type":"WEB","url":"https://github.com/mariocasciaro/object-path/commit/2be3354c6c46215c7635eb1b76d80f1319403c68"},{"type":"PACKAGE","url":"https://github.com/mariocasciaro/object-path"}],"affected":[{"package":{"name":"object-path","ecosystem":"npm","purl":"pkg:npm/object-path"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.11.5"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/10/GHSA-cwx2-736x-mf6w/GHSA-cwx2-736x-mf6w.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:H"}]}
