We apologize to all the maintainers of libraries that depend on @babel/runtime, do not actually trigger the vulnerable code path, and will get bug reports asking to "please upgrade Babel because it's insecure" 😅

It is unlikely that you are affected, as the security vulnerability only applies when passing a user-provided string to the second argument of RegExp.prototype.replace.
