CVE-2025-59465 (GCVE-0-2025-59465)

Vulnerability from cvelistv5 – Published: 2026-01-20 20:41 – Updated: 2026-01-20 20:41

Summary

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) }) }) ```

Severity ?

7.5 (High)

GHSA-W2PG-HW7V-F7M9

Vulnerability from github – Published: 2026-01-20 21:31 – Updated: 2026-01-20 21:31

Details

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)
  })
})

Severity ?

7.5 (High)

  "details": "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:\n```\nserver.on(\u0027secureConnection\u0027, socket =\u003e {\n  socket.on(\u0027error\u0027, err =\u003e {\n    console.log(err)\n  })\n})\n```",
