An attacker can submit a GET request to /api/register/:email, where :email is a base64 encoded e-mail address, to receive confirmation as to whether a user account exists in the system with the specified e-mail address.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.55%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
