The Node.js Permission Model does not clarify in the documentation that
wildcards should be only used as the last character of a file path. For
example: --allow-fs-read=/home/node/.ssh/*.pub
will ignore pub
and give access to everything after .ssh/
. This misleading documentation
affects all users using the experimental permission model in Node.js 20 and
Node.js 21. Please note that at the time this CVE was issued, the
permission model is an experimental feature of Node.js.
