调研方向
Start with the linked rustls advisory and verify whether ev-node includes rustls 0.23.41 or an affected transitive dependency. The advisory identifies version 0.23.45 as patched; determine the repository's remediation point and confirm that the affected version is no longer used after the relevant checks pass.

Rustls accepted TLS 1.3 handshake messages sent at the wrong encryption level
when they followed a key-changing message in the same record. For example,
a plaintext EncryptedExtensions message packed into the same record as the
ServerHello was accepted.
RFC 8446 section 5.1 requires that handshake messages do not span key changes,
and that implementations terminate the connection with an "unexpected_message"
alert if they do.
The handshake transcript is still authenticated, so a network-position attacker
cannot use this to alter or complete a handshake; the practical effect is that
a peer could send handshake messages that should be encrypted in plaintext
without rustls rejecting the connection.
This is functionally the same bug as Go's
GO-2026-4340 (CVE-2025-61730).
