REDHAT-BUG-2431349: High severity npm/node vulnerability

Published Jan 20, 2026
·
Updated

A malformed HTTP/2 HEADERS frame with oversized, invalid HPACK data can cause Node.js to crash by triggering an unhandled TLSSocket error ECONNRESET. Instead of safely closing the connection, the process crashes, enabling a remote denial of service. This primarily affects applications that do not attach explicit error handlers to secure sockets, for example: server.on('secureConnection', socket => { socket.on('error', err => { console.log(err) }) })
