{"cve":"CVE-2018-12120","nvd":{"published":"2018-11-28T17:29:00.290","modified":"2026-10-08T22:16:44.727","status":"Modified","description":"Node.js: All versions prior to Node.js 6.15.0: Debugger port 5858 listens on any interface by default: When the debugger is enabled with `node --debug` or `node debug`, it listens to port 5858 on all interfaces by default. This may allow remote computers to attach to the debug port and evaluate arbitrary JavaScript. The default interface is now localhost. It has always been possible to start the debugger on a specific interface, such as `node --debug=localhost`. The debugger was removed in Node.js 8 and replaced with the inspector, so no versions from 8 and later are vulnerable.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-829","CWE-419"],"references":["http://www.securityfocus.com/bid/106040","https://nodejs.org/en/blog/vulnerability/november-2018-security-releases/","http://www.securityfocus.com/bid/106040","https://nodejs.org/en/blog/vulnerability/november-2018-security-releases/"],"products":["nodejs:node.js"],"source":"nvd","synced_at":"2026-10-19T20:53:59.789560037+00:00"},"epss":{"cve":"CVE-2018-12120","score":0.04277,"percentile":0.91032,"date":"2026-10-25"},"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).
