Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Filament's app-based multi-factor authentication recovery codes, in filament/filament versions 4.0.0 to before 4.11.5 and 5.0.0 to before 5.6.5, can be reused when submitted concurrently, so one code can be used more than once. Email-based MFA is not affected, and the issue only applies when recovery codes are enabled. An attacker would need the user's password and recovery codes, and could then obtain more authenticated sessions than the single-use design implies. Upgrade to filament/filament 4.11.5 or 5.6.5.
