@anupamme Thanks for opening the PR!

I noticed that the PR description and the changes don't match. The description mentions example-apps/docker/collector-latest/package-lock.json, but the actual changes update the root package.json and package-lock.json.

We've already addressed this issue for our production dependencies, and since this isn't customer-facing, I don't think we should merge this as a fix commit. Also, the latest advisory (GHSA-r292-9mhp-454m) has already been addressed.

We'll discuss internally whether we actually want to pin the version before making any further changes.

We really appreciate your contribution and the time you took to investigate and submit the fix!

@anupamme Closing this PR for now. After discussion, we decided not to pin the dependency version at this point, and it also looks like this update is based on an older advisory. Thanks again for taking the time to look into this and submit the PR!
