Basically I found a vulnerability by complete accident that gave me access to people s PII in an IRS authorized e-file app.I disclosed the vulnerability to them, and they ignored me.What s next? I haven t found a way to report this to the IRS directly; everything seems focused on personal exposure. I want to make sure this gets addressed.Anyone have any similar experience or advice?Don t bother asking where or how; I won t be providing that information.
