The two policies differ: omitting `ca` uses the default trust store, while supplying `ca` replaces it. Since they share a key, a TLS session authenticated under the broader default policy is handed to a new connection made under the later `ca: []` policy, and TLS 1.3 session resumption carries the earlier authentication forward, so the second request reports `authorized === true` and transmits confidential data to a server its own CA policy would reject on a fresh connection. This vulnerability affects Node.js 26.x, 24.x, and 22.x."
