CVE-2026-18673Hinoki check available

Configuration disclosure via unauthenticated readiness proxy

Published Aug 12, 2026 · Updated Aug 12, 2026

Information disclosure in kuma-dp 2.14.0 through 2.14.1 allows remote attackers to read data-plane configuration through TCP port 9902. The readiness service binds to all interfaces and forwards non-readiness requests to the Unix-socket Envoy admin API without authenticating callers. Exploitation requires network reachability to port 9902; exposed data includes configuration, listeners, clusters, statistics, and the trust bundle, but not private keys or write access.
