Overview
Affected versions of this package are vulnerable to Protection Mechanism Failure in the DNS request handling process. An attacker can bypass domain name filtering by crafting a DNS request containing multiple questions, where the first question appears legitimate but subsequent questions are used to evade the filter. This is only exploitable if the remote DoH server supports multiple questions in a single DNS request and the attacker can craft such requests locally.
