HIGH 7.5 Microsoft
CVE-2023-32559
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.
