CVE-2026-45674 is an improper DNS response-validation vulnerability in Netty's netty-resolver-dns component. Prior to Netty 4.1.135.Final and 4.2.15.Final, DnsResolveContext does not validate the bailiwick (origin authority) of CNAME records before accepting and caching them. A malicious or spoofed DNS response can therefore introduce CNAME data outside the authoritative scope of the queried domain, enabling DNS cache poisoning and subsequent resolution of names to attacker-selected destinations.
