CVE-2026-18679

5.8 medium SSVC exploitation: none Awaiting Analysis
NVD · CVE.org

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.

Fix

Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
