Really Simple Security < 9.8.1 - Unauthenticated 2FA Bypass via Email Provider State Demotion
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
The Really Simple Security WordPress plugin before 9.8.1 does not prevent an unauthenticated request from resetting an account's completed email two-factor enrolment, allowing an attacker who already knows the account's password to bypass the second factor and obtain that user's session, up to administrator.
