$ node cve-2026-63643.js
The /calendar Socket.IO namespace accepts an ADD_CALENDAR event with a user-controlled url parameter. The server fetches this URL without validation, allowing requests to internal services:
socket.emit("ADD_CALENDAR", { url: "http://internal-service/" });
CVE-2026-63643 extends this with selfSignedCert: true to bypass TLS verification and exfiltrate iCal content from internal calendars.
