CVE-2026-52688: Insufficient Verification of Data Authenticity in PowerDNS RecursorCVE-2026-52688 0 RRSIGs with too few labels can lead to bypass of DNSSEC wildcard validation Join the discussion | CVE Database V5 | 07/23/2026, 08:03:58 UTC Added: 07/23/2026, 08:37:35 UTC |
CVE-2026-52686: Insufficient Verification of Data Authenticity in PowerDNS RecursorCVE-2026-52686 0 The issue is a DNSSEC validation bypass where wildcard expansion proofs (NSEC/NSEC3 records) are accepted without signature validation when the wildcard answer is a CNAME or DNAME record.

CVE-2026-52684: Time-of-check Time-of-use (TOCTOU) Race Condition in PowerDNS RecursorCVE-2026-52684 0 If the auth responds very slowly and the records expire in between, the capping of TTLs is not enforced for lack of data. This does not happen on regular resolve as then then the child records are used immediately if not expired and thus valid, or the records are expired, and in that case not used. So this case can only happen if almost expired records are used to refresh the authoritative NS records.
