referenced in the USN-6822-1 advisory.

    It was discovered that Node.js incorrectly handled certain inputs when it is using the policy mechanism.
    If a user or an automated system were tricked into opening a specially crafted input file, a remote
    attacker could possibly use this issue to bypass the policy mechanism. (CVE-2023-32002, CVE-2023-32006)

    It was discovered that Node.js incorrectly handled certain inputs when it is using the policy mechanism.
    If a user or an automated system were tricked into opening a specially crafted input file, a remote
    attacker could possibly use this issue to perform a privilege escalation. (CVE-2023-32559)
