GHSA-676x-f7gg-47vc: Netty Vulnerable to DNS Cache Poisoning via Missing Bailiwick Checks in CNAME RecordsCVE-2026-45674 0 Netty's DNS resolver component (DnsResolveContext) fails to validate the origin (bailiwick) of CNAME records in DNS responses, leading to potential DNS cache poisoning via bailiwick bypass. This vulnerability affects applications using Netty's DNS resolver. The issue arises because the resolver blindly caches all CNAME records from DNS answers without verifying that the data originates from an authoritative source for the queried domain or its parent domains, violating recommended DNS security practices. This can allow attackers to poison DNS caches, potentially causing clients to resolve to malicious IP addresses.
