Impact
An attacker who possesses a valid authentication provider token and a single MFA recovery code or SMS one-time password can create multiple authenticated sessions by sending concurrent login requests via the authData login endpoint. This defeats the single-use guarantee of MFA recovery codes and SMS one-time passwords, allowing session persistence even after the legitimate user revokes detected sessions.
Patches
The fix adds optimistic locking to the authData login path, ensuring that concurrent database updates for the same user fail when the original MFA token array has already been modified by another request.
