CVE-2018-16886 not yet assigned priority: Debian including 1 source packages (etcd), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
etcd versions 3.2.x before 3.2.26 and 3.3.x before 3.3.11 are vulnerable to an improper authentication issue when role-based access control (RBAC) is used and client-cert-auth is enabled. If an etcd client server TLS certificate contains a Common Name (CN) which matches a valid RBAC username, a remote attacker may authenticate as that user with any valid (trusted) client certificate in a REST API request to the gRPC-gateway.
