+CVE-2019-19844: Potential account hijack via password reset form
+================================================================
+
+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.
