GHSA-r3j6-gpjw-qfjr: filament/filament (CVE-2026-84306)

filament/filament	Packagist	>=4.0.0, <4.12.6 \|\| >=5.0.0, <5.7.6	4.12.6, 5.7.6

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Filament's app-based multi-factor authentication (filament/filament, versions 4.0.0 to before 4.12.6 and 5.0.0 to before 5.7.6) accepts a one-time code that was issued earlier even after a newer code has already been used. Email-based MFA is not affected. An attacker who already knows a user's password and has one valid one-time code could reuse that code within its time window, which is about four minutes on default settings, even after the legitimate user has logged in. Upgrade to version 4.12.6 or 5.7.6.
