The vulnerability allows a remote attacker to bypass upload filters.
The vulnerability exists due to interpretation conflict in the @hapi/content header parser when parsing duplicate Content-Disposition or Content-Type parameters. A remote attacker can send a specially crafted request with duplicate header parameters to bypass upload filters.
