What an attacker can do

Unauthenticated network-accessible attackers can bypass the DNS-based IP blocklist by exploiting incomplete address validation in the url_is_blacklisted function, which inspects only the first resolved address while the underlying HTTP client iterates all cached addresses. Vendor/CNA’s CVSS 4.0 assessment (base score 7.7/10) rates confidentiality, integrity and availability impact as none.
