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.

Impacts

This vulnerability affects all users using the experimental policy mechanism in all active release lines: 16.x, 18.x and, 20.x.
