Researchers investigating the Rails parameter parsing vulnerability discovered that the same or similar vulnerable code had made its way into multiple other libraries. If your application uses these libraries to process untrusted data, it may still be vulnerable even if you have upgraded Rails. Check your Gemfile and Gemfile.lock for vulnerable versions of the following libraries, and if you are using one, update it immediately.
You can update each of these by using "bundle update <gem name>".

yikes, a few of these are really popular gems. I have a feeling we're going to see more gems in the upcoming weeks that have this same issue. Please keep posting these security alerts!
Thanks for keeping us up to date. I would rather have too many emails/notifications than miss something important.
