This may allow remote computers to attach to the debug port and evaluate arbitrary JavaScript.

HIGH 8.1EPSS 4.28%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (4.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Node.js: All versions prior to Node.js 6.15.0: Debugger port 5858 listens on any interface by default: When the debugger is enabled with `node --debug` or `node debug`, it listens to port 5858 on all interfaces by default. This may allow remote computers to attach to the debug port and evaluate arbitrary JavaScript. The default interface is now localhost. It has always been possible to start the debugger on a specific interface, such as `node --debug=localhost`. The debugger was removed in Node.js 8 and replaced with the inspector, so no versions from 8 and later are vulnerable.
