An attacker can pass crafted paths which cause Lodash to delete methods from global prototypes. The issue permits deletion of properties but does not allow overwriting their original behavior. The issue is patched from 4.17.23 to 4.18.0 depending on the package: lodash, lodash-es, and lodash-amd in 4.17.23, and the standalone lodash.unset and lodash.omit packages in 4.18.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:H/SI:H/SA:H/E:P","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-1321"],"references":["https://cna.openjsf.org/security-advisories.html","https://github.com/lodash/lodash/security/advisories/GHSA-xxjr-mmjv-4gpg","https://access.redhat.com/errata/RHSA-2026:11414","https://access.redhat.com/errata/RHSA-2026:13542","https://access.redhat.com/errata/RHSA-2026:13548"],"products":["lodash:lodash"],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2025-13465","score":0.01823,"percentile":0.78633,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-xxjr-mmjv-4gpg","url":"https://osv.dev/vulnerability/GHSA-xxjr-mmjv-4gpg","summary":"Lodash has Prototype Pollution Vulnerability in `_.unset` and `_.omit` functions","modified":"2026-10-17T02:55:54.229635593Z","packages":[{"ecosystem":"npm","name":"lodash","purl":"pkg:npm/lodash","ranges":[">=4.0.0 <4.17.23"],"fixed":["4.17.23"]},{"ecosystem":"npm","name":"lodash.unset","purl":"pkg:npm/lodash.unset","ranges":[">=4.0.0 <=4.5.2"],"fixed":[]},{"ecosystem":"npm","name":"lodash-es","purl":"pkg:npm/lodash-es","ranges":[">=4.0.0 <4.17.23"],"fixed":["4.17.23"]},{"ecosystem":"npm","name":"lodash-amd","purl":"pkg:npm/lodash-amd","ranges":[">=4.0.0 <4.17.23"],"fixed":["4.17.23"]}]}],"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).
