Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Affected: node-forge versions before 1.4.1, specifically the TLS implementation created by forge.tls.createConnection(). A peer that can reach a forge TLS endpoint, without authentication, can send 18 bytes during the handshake, a fragmented handshake record followed by a record of another content type, which makes process() throw an uncaught TypeError. In Node.js applications that call process() from a socket data handler, as the documented usage does, this terminates the process. Upgrade to node-forge 1.4.1, which returns cleanly after the fatal unexpected_message alert.
