LowCVSS 3.7/10Last modified Nov 10, 2026

Description

The validating recursor in Hickory DNS hickory-recursor 0.25.0 through 0.26.0-alpha.1, hickory-resolver 0.26.0-alpha.1 before 0.26.2, and hickory-net 0.26.0-beta.1 before 0.26.2 caches DNSSEC-bogus answers using the untrusted, attacker-supplied record TTL (capped at 24 hours) instead of a short validation-failure TTL. A remote attacker who spoofs a single authoritative response with an invalid signature and a long TTL can keep the bogus result cached for up to 24 hours.
