## Affected

- reallysimpleplugins Really Simple Security: fixed in 9.8.2

## Description

Really Simple Security plugin for WordPress before 9.8.2 contains a missing authorization check vulnerability that allows authenticated low-privileged attackers to bypass enforced two-factor authentication indefinitely by exploiting an unguarded code path in the profile-page update handler. Attackers can submit a crafted POST request without the two-factor-authentication field to skip nonce verification and trigger delete_two_fa_meta(), which resets the grace period anchor timestamp on every login cycle, causing mandatory 2FA enforcement to be deferred indefinitely.
