### Impact

When multi-factor authentication (MFA) via TOTP is enabled for a user account, Parse Server generates two single-use recovery codes. These codes are intended as a fallback when the user cannot provide a TOTP token. However, recovery codes are not consumed after use, allowing the same recovery code to be used an unlimited number of times. This defeats the single-use design of recovery codes and weakens the security of MFA-protected accounts.

An attacker who obtains a single recovery code can repeatedly authenticate as the affected user without the code ever being invalidated.

### Patches

The fix ensures that each recovery code is removed from the stored recovery code list after a successful login.

### Workarounds

There is no known workaround.
