CVE-2026-18678

When an operator adds an HTTPS control plane profile to kumactl without providing a CA certificate, kumactl disables TLS verification and sends API tokens over the unverified connection. An attacker on the network path between the operator and the control plane can intercept user or admin API...

The default kuma-cp configuration in Kong Mesh reveals the admin bootstrap token and signing keys to any webpage the operator visits while the control plane is reachable from their browser. Due to a CORS misconfiguration a cross-origin fetch from a malicious page returns the admin JWT and signing...

CVE-2026-18676 Kong Mesh: default control plane config leaks the admin token cross-origin via a CORS wildcard and localhost admin

The default kuma-cp configuration in Kong Mesh reveals the admin bootstrap token and signing keys to any webpage the operator visits while the control plane is reachable from their browser. Due to a CORS misconfiguration a cross-origin fetch from a malicious page returns the admin JWT and signing...

CVE-2026-18675

The vulnerability CVE-2026-18675 affects Kuma Kuma CP’s dataplane token validator, which uses an unchecked Go type assertion on the JWT kid header. If a token’s kid is a JSON number, it decodes as a float64 and triggers a runtime panic before signatures, claims, or authorization checks run. This ...

CVE-2026-18675 Kong Mesh: control plane denial of service via a malformed dataplane token with a non-string JWT kid

The dataplane token validator in kuma-cp performs an unchecked Go type assertion on the JWT kid header. A token whose kid is a JSON number decodes as a float64 and triggers a runtime panic before any signature, claims, or authorization check runs. The panic terminates the entire kuma-cp process,...

PT-2026-71218

When kuma-dp is started against an HTTPS control plane and the operator did not pass a CA certificate, the data plane connects with TLS peer verification disabled, and the dataplane authentication token is sent over that unverified connection. An on-path actor can intercept the dataplane...

etcd: etcd: Denial of Service via unbounded TLS handshake goroutines

A flaw was found in etcd, a distributed key-value store. A remote attacker can exploit this by opening numerous TCP connections to an etcd TLS listener without completing the TLS handshake. This action causes the tlsListener.acceptLoop to spawn an unbounded number of goroutines, which consume...
