{"id":"UBUNTU-CVE-2019-16776","details":"Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary File Write. It fails to prevent access to folders outside of the intended node_modules folder through the bin field. A properly constructed entry in the package.json bin field would allow a package publisher to modify and/or gain access to arbitrary files on a user's system when the package is installed. This behavior is still possible through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option.","modified":"2026-01-20T17:08:10.702097Z","published":"2019-12-13T01:15:00Z","upstream":["CVE-2019-16776"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-16776"},{"type":"REPORT","url":"https://github.com/npm/cli/security/advisories/GHSA-x8qc-rrcw-4r46"},{"type":"REPORT","url":"https://blog.npmjs.org/post/189618601100/binary-planting-with-the-npm-cli"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-16776"}],"affected":[{"package":{"name":"npm","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/npm@1.3.10~dfsg-1?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.18~dfsg-3","1.3.10~dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"npm","binary_version":"1.3.10~dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-16776.json"}},{"package":{"name":"npm","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/npm@3.5.2-0ubuntu4.1.16.04.1~esm1?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.21+ds-2","3.5.2-0ubuntu4","3.5.2-0ubuntu4.1.16.04.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"npm","binary_version":"3.5.2-0ubuntu4.1.16.04.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-16776.json"}},{"package":{"name":"npm","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/npm@3.5.2-0ubuntu4.1.18.04.1~esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.5.2-0ubuntu4","3.5.2-0ubuntu4.1.18.04.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"npm","binary_version":"3.5.2-0ubuntu4.1.18.04.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-16776.json"}},{"package":{"name":"npm","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/npm@6.14.4+ds-1ubuntu2?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.8.0+ds6-4","6.14.4+ds-1ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_name":"npm","binary_version":"6.14.4+ds-1ubuntu2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-16776.json"}},{"package":{"name":"npm","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/npm@8.5.1~ds-1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7.5.2+ds-2","7.24.2+ds-1","7.24.2+ds-2","8.3.0~ds-1","8.3.0~ds-2","8.3.2~ds-1","8.5.0~ds-1","8.5.1~ds-1"],"ecosystem_specific":{"binaries":[{"binary_name":"npm","binary_version":"8.5.1~ds-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-16776.json"}},{"package":{"name":"npm","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/npm@9.2.0~ds1-2?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.2.0~ds1-1","9.2.0~ds1-2"],"ecosystem_specific":{"binaries":[{"binary_name":"npm","binary_version":"9.2.0~ds1-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-16776.json"}},{"package":{"name":"npm","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/npm@9.2.0~ds1-3?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["9.2.0~ds1-3"],"ecosystem_specific":{"binaries":[{"binary_name":"npm","binary_version":"9.2.0~ds1-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-16776.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
