CVE-2026-33190

CoreDNS TSIG authentication bypass vulnerability (CVE-2026-33190) affects versions prior to 1.14.3 on non-plain-DNS transports. The tsig plugin trusts the transport writer’s TsigStatus() instead of verifying TSIG itself, causing unauthenticated remote access over DoT, DoH, DoH3, DoQ, and gRPC. Do...

Missing Critical Step in Authentication

Overview github.com/coredns/coredns/core/dnsserver is a package that implements all the interfaces from Caddy, so that CoreDNS can be a servertype plugin. Affected versions of this package are vulnerable to Missing Critical Step in Authentication in the TSIG authentication process for gRPC, QUIC,...

CoreDNS has TSIG authentication bypass on gRPC and QUIC transports

Summary The gRPC, QUIC, DoH, and DoH3 transports in CoreDNS incorrectly handle TSIG authentication. For gRPC and QUIC, CoreDNS checks whether the TSIG key name exists in the config, but does not actually verify the TSIG HMAC. If the key name matches, tsigStatus remains nil and the tsig plugin...

GHSA-QHMP-Q7XH-99RH CoreDNS has TSIG authentication bypass on DoT, DoH, DoH3, DoQ, and gRPC

Summary CoreDNS' tsig plugin can be bypassed on non-plain-DNS transports because it trusts the transport writer's TsigStatus instead of performing verification itself. In the attached PoC, plain DNS/TCP correctly rejects an invalid TSIG NOTAUTH, while the same invalid-TSIG request is accepted ove...
