A flaw in the handling of recovery codes for app-based multi-factor authentication allows the same recovery code to be reused indefinitely. This issue does not affect email-based MFA. It also only applies when recovery codes are enabled.
If an attacker gains access to both the user's password and their recovery codes, they can repeatedly complete MFA without the user's app-based second factor. This weakens the expected security of MFA by turning recovery codes into a static, long-term bypass method.
