The vulnerability is limited to the `includeInheritedProps` mode (if version >= 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 >= 0.11.0 is used. Any usage of `set()` in versions < 0.11.0 is vulnerable. The issue is fixed in object-path version 0.11.5 As a workaround, don't use the `includeInheritedProps: true` options or the `withInheritedProps` instance if using a version >= 0.11.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-20","CWE-471"],"references":["https://github.com/mariocasciaro/object-path/commit/2be3354c6c46215c7635eb1b76d80f1319403c68","https://github.com/mariocasciaro/object-path/security/advisories/GHSA-cwx2-736x-mf6w","https://github.com/mariocasciaro/object-path/commit/2be3354c6c46215c7635eb1b76d80f1319403c68","https://github.com/mariocasciaro/object-path/security/advisories/GHSA-cwx2-736x-mf6w"],"products":["object-path_project:object-path"],"source":"nvd","synced_at":"2026-10-19T21:09:53.489947993+00:00"},"epss":{"cve":"CVE-2020-15256","score":0.01546,"percentile":0.75007,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cwx2-736x-mf6w","url":"https://osv.dev/vulnerability/GHSA-cwx2-736x-mf6w","summary":"Prototype pollution in object-path","modified":"2026-07-08T06:00:47.441827685Z","packages":[{"ecosystem":"npm","name":"object-path","purl":"pkg:npm/object-path","ranges":["<0.11.5"],"fixed":["0.11.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
