Mitigation checklist

Recommended fix / mitigation

Applications using the `re2` Node.js bindings should ensure that the `lastIndex` property of regular expression objects is not directly influenced by untrusted external input. As an operational control, developers should either avoid assigning `lastIndex` from untrusted input or clamp its value to the subject's string length (`str.length`) before performing regex operations on non-ASCII subjects.
