Description

Parse Server's MFA recovery codes not consumed after use

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.
