CVE-2026-123593CVE-2026-123593
Description
Hickory DNS hickory-net 0.26.0-beta.1 before 0.26.2 and hickory-proto 0.24.0 through 0.26.0-alpha.1 compare DNSKEY public keys against DNSSEC trust anchors without checking the DNSKEY record name, so an RRset made up only of trusted keys is accepted without RRSIG verification. Attackers able to spoof or control name server responses can replace a secure zone's DNSKEY RRset with the root zone's keys, and use a large TTL to keep it cached.
