Overview
Affected versions of this package are vulnerable to Improper Certificate Validation in https.Agent.prototype.getName(), which gives a request that omits ca and a request that supplies ca: [] the same Agent and session-cache key. A MitM attacker can receive confidential data from a request made under the ca: [] policy, because TLS 1.3 session resumption reuses a session authenticated under the default trust store, so the request reports authorized === true for a server its own CA policy rejects on a fresh connection. Only applications that make a request without ca and a later request with ca: [] through the same https.Agent to the same server are affected.
