By submitting a suitably crafted email address making use of Unicode characters, that compared equal to an existing user email when lower-cased for comparison, an attacker could be sent a password reset token for the matched account.
In order to avoid this vulnerability, password reset requests now compare the submitted email using the stricter, recommended algorithm for case-insensitive comparison of two identifiers from Unicode Technical Report 36, section 2.11.2(B)(2). Upon a match, the email containing the reset token will be sent to the email address on record rather than the submitted address.
