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

Vulnerability from cvelistv5 – Published: 2026-01-20 20:41 – Updated: 2026-06-30 12:07
VLAI?
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)
