The vulnerability is a missing authorization check (CWE-862) in the profile-page update handler of Really Simple Security before 9.8.2. An authenticated low-privileged attacker can submit a POST request that omits the two-factor-authentication field, bypassing nonce verification and triggering the delete_two_fa_meta() function. This function resets the grace period anchor timestamp on every login cycle, indefinitely deferring mandatory 2FA enforcement. The attack requires network access and valid authentication credentials but no additional user interaction. The fix is available in version 9.8.2 and later.
