CWE-330 Open this link in a new tab

How to fix?

Upgrade uuid to version 1.3.1 or higher.

Overview

uuid is RFC4122 (v1 and v4) generator.

Affected versions of the package use the Math.random() function which may generate already-used numbers after 24,000 cycles, making the values predictable for objects requiring unpredictability. It is possible for an attacker to guess the next value to be generated and may use this to access sensitive information.
