This was a result of building with V8 snapshots enabled by default which caused the initially randomized seed to be overwritten on startup.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-20"],"references":["http://www.securityfocus.com/bid/99959","https://access.redhat.com/errata/RHSA-2017:2908","https://access.redhat.com/errata/RHSA-2017:3002","https://nodejs.org/en/blog/vulnerability/july-2017-security-releases/","http://www.securityfocus.com/bid/99959"],"products":["nodejs:node.js"],"source":"nvd","synced_at":"2026-10-19T20:44:47.710380879+00:00"},"epss":{"cve":"CVE-2017-11499","score":0.05434,"percentile":0.92715,"date":"2026-10-31"},"kev":null,"osv":[],"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).
