All versions of the UUID npm package < 7 have been deprecated due to a weakness in Math.random(). There are two packages in this repository that use the deprecated version.

• https://github.com/actions/toolkit/blob/main/packages/tool-cache/package.json#L44
• https://github.com/actions/toolkit/blob/main/packages/cache/package.json#L48

Any downstream package that depends on these packages will include the following line in their package-lock.json:

      "deprecated": "Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.",

Can you upgrade node UUID to the latest released version? Happy to submit a PR to help you out.
