{"id":"CVE-2019-16777","aliases":["GHSA-4328-8hgf-7wjr"],"url":"https://o3.security/vulnerability/CVE-2019-16777","summary":"npm Vulnerable to Global node_modules Binary Overwrite","details":"Versions of  the npm CLI prior to 6.13.4 are vulnerable to a Global node_modules Binary Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. \n\nFor example, if a package was installed globally and created a `serve` binary, any subsequent installs of packages that also create a `serve` binary would overwrite the first binary. This will not overwrite system binaries but only binaries put into the global node_modules directory.\n\nThis behavior is still allowed in local installations and also through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option.\n\n\n## Recommendation\n\nUpgrade to version 6.13.4 or later.","published":"2019-12-13T01:15:11.007Z","modified":"2026-10-29T11:12:11.110166005Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"npm","fixedVersion":"6.13.4"}],"fix":null,"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Z36UKPO5F3PQ3Q2POMF5LEKXWAH5RUFP/"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00027.html"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHEA-2020:0330"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0573"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0579"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0597"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0602"},{"type":"ADVISORY","url":"https://blog.npmjs.org/post/189618601100/binary-planting-with-the-npm-cli"},{"type":"ADVISORY","url":"https://github.com/npm/cli/security/advisories/GHSA-4328-8hgf-7wjr"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202003-48"},{"type":"ADVISORY","url":"https://www.oracle.com/security-alerts/cpujan2020.html"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-16777"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-4328-8hgf-7wjr"},{"type":"PACKAGE","url":"https://github.com/npm/cli"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/Z36UKPO5F3PQ3Q2POMF5LEKXWAH5RUFP"},{"type":"WEB","url":"https://www.npmjs.com/advisories/1437"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-29T11:12:11.110166005Z"}}
