CVE-2025-59465

Severity CVSS v4.0:
Pending analysis
Type:
CWE-400 Uncontrolled Resource Consumption ('Resource Exhaustion')
Publication date:

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:<br /> ```<br /> server.on(&amp;#39;secureConnection&amp;#39;, socket =&gt; {<br /> socket.on(&amp;#39;error&amp;#39;, err =&gt; {<br /> console.log(err)<br /> })<br /> })<br /> ```
