CVE ID :CVE-2026-123599
Published : Nov. 8, 2026, 1:38 a.m. | 19 minutes ago
Description :Hickory DNS hickory-proto before 0.26.0-beta.1 and hickory-net before 0.26.2 contain a DNSSEC validation bypass because verify_rrsets() ignores DNS class when partitioning RRsets, so non-IN records skip signature verification yet are marked secure when the IN records verify. Attackers able to supply DNS responses can include forged CH or HS class records, including DS records, to authenticate any DNSKEY and forge child zone responses.
Severity: 6.3 | MEDIUM
