Zero-Day Exploits / Vulnerabilities
A server-rendered, source-attributed view of confirmed CISA KEV entries and all NVD CVEs published in the rolling 48-hour UTC window.
Important distinction: CISA KEV means exploitation has been observed; it does not mean every entry was a zero-day. An NVD publication in the past 48 hours does not mean exploitation has occurred. Source records describe third-party products and do not identify Kythos AI customers, contracts, affiliations, or work history.

CVE-2026-123594
Hickory DNS hickory-proto through 0.26.0-alpha.1 and hickory-net 0.26.0-beta.1 before 0.26.2 contain an NSEC validation flaw that returns a secure proof for NXDOMAIN responses when the covering NSEC's Next Domain Name is a strict descendant of the query name, which actually proves the name exists as an…
CVE-2026-123593
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…
CVE-2026-123592
The hickory-net crate in Hickory DNS 0.26.0-beta.1 before 0.26.2 allows DNSSEC validation bypass because Name's Hash ignores label lengths and ValidationCacheKey compares only that hash. An attacker controlling an unsigned delegation whose name differs from a signed target only in dot positions can prime an Insecure…
CVE-2026-123591
Hickory DNS hickory-net 0.26.0-beta.1 before 0.26.2 and hickory-proto through 0.26.0-alpha.1 fail to verify, per RFC 6840 §4.4, that an NSEC or NSEC3 record denying a DS RRset also proves the delegation's NS record exists. Attackers can reuse child-side NSEC or NSEC3 records to fake an insecure…
CVE-2026-123590
Hickory DNS hickory-net 0.26.0-beta.1 before 0.26.2 and hickory-proto through 0.26.0-alpha.1 accept NSEC and NSEC3 records for DNSSEC nonexistence proofs when any other record with the same owner name passes signature validation. Attackers able to supply DNS responses can mix validly signed records with bogus same-name NSEC…
CVE-2026-123589
The DNS-over-QUIC (DoQ) server in hickory-server (hickory-dns) before 0.26.2 does not apply any timeout when reading a request message from a QUIC stream, bypassing all configured timeouts.

CVE-2026-123588
The recursive resolver in Hickory DNS (all versions of the hickory-recursor crate, and hickory-resolver 0.26.0 before 0.26.2) caches an empty connection pool when it follows a referral with no glue records and all queries for the name servers' IP addresses fail. An attacker able to spoof…
CVE-2026-123587
The DNSSEC validation in the Hickory DNS hickory-net crate 0.26.0 before 0.26.2 identifies wraparound NSEC records by comparing the next domain name to an SOA record in the response, accepting that SOA even if it fails validation. Attackers who can supply DNS responses can combine a…
CVE-2026-123586
Hickory DNS 0.25.0-alpha.3 through 0.25.2 contains a query amplification vulnerability in its recursive resolver, which mishandles cyclic sibling name server referrals that lack glue records.

CVE-2026-123585
The hickory-resolver component of Hickory DNS 0.25.0 before 0.26.2 follows irrelevant CNAME records when resolving recursive queries, sending queries that are unnecessary to answer the original request.

CVE-2026-123584
The hickory-net crate in Hickory DNS 0.26.0 before 0.26.2 stops listening and returns an error when a client UDP connection receives a datagram that cannot be parsed as a DNS message. Remote attackers who guess the query's source port, without knowing the transaction ID, can spoof…
CVE-2026-123583
The recursive resolver in Hickory DNS hickory-recursor 0.25.0 through 0.25.2 and hickory-resolver 0.26.0 before 0.26.2 does not apply out-of-bailiwick filtering to negative responses. Attackers able to supply crafted negative responses can include out-of-bailiwick records to facilitate cache poisoning and more easily exploit other DNSSEC verification flaws.
CVE-2026-123582
The validating recursive resolver and validating forwarder in Hickory DNS (hickory-server) 0.25.0 before 0.26.2 do not check whether the SOA record passed DNSSEC validation when assembling NXDOMAIN or NODATA responses. An attacker able to supply forged DNS responses can have a forged SOA record returned to…
CVE-2026-123581
Hickory DNS hickory-proto through 0.26.0-alpha.1 and hickory-net 0.26.0-beta.1 before 0.26.2 contain a DNSSEC validation flaw that accepts a response as a positive answer when any valid RRset appears in the answer section, without checking that the RRset is responsive to the query. Attackers can supply signed…
CVE-2026-123580
Hickory DNS hickory-net 0.26.0-beta.1 before 0.26.2 and hickory-proto through 0.26.0-alpha.1 perform insufficient checks on NSEC3 record names during DNSSEC verification, comparing only the hashed label without confirming the record belongs to the correct zone. Attackers can supply NSEC3 records from another zone with a matching hash…
CVE-2026-123579
DNSSEC validation in Hickory DNS hickory-net 0.26.0-beta.1 before 0.26.2 and hickory-proto through 0.26.0-alpha.1 does not distinguish NODATA responses from wildcard-expanded positive responses.

CVE-2026-123578
Hickory DNS hickory-net 0.26.0 before 0.26.2 and hickory-proto 0.25.0 through 0.25.2 skip the check that a UDP response's question section matches the query when the response has an empty question section (QDCOUNT=0), and also skip the case-randomization check. Remote attackers able to inject spoofed UDP responses…
CVE-2026-123577
Hickory DNS from 0.24.0 before 0.26.2 contains a resource exhaustion vulnerability that allows remote attackers to consume server memory via unbounded DoH request bodies.
