Stop talking about it and call a law firm. Your local Bar Association will be able to give you a list of firms/attorneys that practice in this area, or your existing lawyer may have a recommendation. Many law firms will give you a short consultation for free. Bring a succinct written summary of the facts with you that briefly describes the product, how you discovered the issue, and what you found when you investigated, with dates. Include a list of evidence items you have already collected. Litigation is difficult and expensive, but if you have a strong case (and it sounds like you do) then the law firm may take it on contingency in return for a larger portion of the settlement/judgment.
EDIT: I wouldn't trust the opinions of the 'just execute better' posters here, considering your competitors' employees already infiltrated your slack channel.
