Vulnerability description
DayBreach CVE AI Research
CVE-2026-18679 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
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 authentication token and impersonate the control plane to the data plane, injecting a forged bootstrap configuration and taking over the proxy.
