CVE-2025-59465
Good to know:
Date: January 20, 2026
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) }) })
