{"id":"UBUNTU-CVE-2023-32559","details":"A privilege escalation vulnerability exists in the experimental policy mechanism in all active release lines: 16.x, 18.x and, 20.x. The use of the deprecated API `process.binding()` can bypass the policy mechanism by requiring internal modules and eventually take advantage of `process.binding('spawn_sync')` run arbitrary code, outside of the limits defined in a `policy.json` file. Please note that at the time this CVE was issued, the policy is an experimental feature of Node.js.","modified":"2026-04-22T16:45:02.580938Z","published":"2023-08-24T02:15:00Z","related":["USN-6822-1"],"upstream":["CVE-2023-32559"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-32559"},{"type":"REPORT","url":"https://nodejs.org/en/blog/vulnerability/august-2023-security-releases#permissions-policies-can-be-bypassed-via-processbinding-mediumcve-2023-32559"},{"type":"REPORT","url":"https://github.com/nodejs/node/commit/d4570fae358693b8f7fec05294b9bb92a966226d"},{"type":"REPORT","url":"https://github.com/nodejs/node/commit/4aa0eff787c14f14a239cf2f44bf751a0151e3eb"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-32559"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6822-1"}],"affected":[{"package":{"name":"nodejs","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/nodejs@12.22.9~dfsg-1ubuntu3.6?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"12.22.9~dfsg-1ubuntu3.6"}]}],"versions":["12.22.5~dfsg-5ubuntu1","12.22.7~dfsg-2ubuntu1","12.22.7~dfsg-2ubuntu3","12.22.9~dfsg-1ubuntu2","12.22.9~dfsg-1ubuntu3","12.22.9~dfsg-1ubuntu3.1","12.22.9~dfsg-1ubuntu3.2","12.22.9~dfsg-1ubuntu3.3","12.22.9~dfsg-1ubuntu3.4","12.22.9~dfsg-1ubuntu3.5"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"libnode72","binary_version":"12.22.9~dfsg-1ubuntu3.6"},{"binary_name":"nodejs","binary_version":"12.22.9~dfsg-1ubuntu3.6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-32559.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
