CVE-2026-58211: CWE-863: Incorrect Authorization in nats-io nats-serverCVE-2026-58211
0

NATS Server versions prior to 2.14.3 and 2.12.12 contain an incorrect authorization vulnerability. A client could be registered as the configured no_auth_user via a parser path triggered when the first client operation was not CONNECT. This bypasses user-level connection restrictions such as allowed_connection_types or proxy_required that normal authentication would enforce. The issue is fixed in versions 2.14.3 and 2.12.12.
