Access: No account. Anyone who can send a request to an app that uses the affected code.
Conditions: It only works under specific conditions the attacker does not fully control (CVSS rates the attack as high complexity).

CVSS vector (scored by GitHub): CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N

Your app is only exposed if it uses the affected part of filament/filament. The advisory below says which part that is. If you are not sure, upgrade anyway: it costs less than finding out.

How to fix CVE-2026-84307 in filament/filament

Find the installed version: composer show filament/filament. If you never required it yourself, composer why filament/filament shows which package pulls it in.
Update it: composer update filament/filament --with-all-dependencies. You need the fixed version for your release line (4.12.5 and 5.7.5).
If Composer will not go that high, your composer.json constraint is holding it back. Widen it (for example "filament/filament": "^5.7.5" if you can take that version), or upgrade the package that requires it.
Run composer audit. It reads the same advisory data and should no longer list CVE-2026-84307.
Commit composer.lock and deploy it. On the server, run composer install --no-dev from the lock file, not composer update.

If you cannot upgrade yet

General hardening for user enumeration issues while the upgrade waits. None of it replaces the fix.

Rate-limit login and password-reset endpoints and return the same response for unknown and known users.
If your app does not use the affected feature, note that in your audit, but still plan the upgrade.

The CVE-2026-84307 advisory

Filament is a collection of full-stack components for accelerated Laravel development. From 4.0.0 until 4.12.5 and 5.7.5, packages/panels/src/Auth/Pages/Login.php presents the multi-factor authentication challenge before evaluating canAccessPanel(). For an account that canAccessPanel() denies, submitting the correct password renders the MFA challenge while an incorrect password returns the generic authentication failure, allowing an unauthenticated attacker to confirm whether a candidate password is valid for that account. When email-based MFA is configured, the correct-password path also sends a login code to the account holder. The issue applies only to accounts that have MFA enabled and are denied panel access. Authentication is not bypassed because canAccessPanel() still runs after the challenge, and no session is created. This issue is fixed in versions 4.12.5 and 5.7.5.

Description from the CVE record, published by GitHub (the CVE Numbering Authority), via the NVD entry for CVE-2026-84307. Advisory title: “Filament: Password validity disclosure for accounts denied panel access on login page”.
