How to fix?

Upgrade node to version 18.19.1, 20.11.1, 21.6.2 or higher.

Overview

node is a JavaScript runtime built on Chrome's V8 JavaScript engine.

Affected versions of this package are vulnerable to Observable Timing Discrepancy due to the implementation of PKCS#1 v1.5 padding. An attacker can infer the private key used in the cryptographic operation by observing the time taken to execute cryptographic operations (Marvin).
