Description

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) }) }) ```

Affected configurations

• nodejs node.js (>= 20.0.0 < 20.20.0) • nodejs node.js (>= 22.0.0 < 22.22.0) • nodejs node.js (>= 24.0.0 < 24.13.0) • nodejs node.js (>= 25.0.0 < 25.3.0)
