CVE-2026-84306 · Filament: Multi-factor authentication (app) codes can still be used after a newer code has been used

Esta página presenta datos de fuentes públicas de vulnerabilidades. Consulta el aviso original antes de actualizar.

Filament is a collection of full-stack components for accelerated Laravel development. From 4.0.0 until 4.12.6 and 5.7.6, packages/panels/src/Auth/MultiFactor/App/AppAuthentication.php uses AppAuthentication::verifyCode() with a used-code cache key derived from both the app authentication secret and the submitted TOTP code. This isolates the newest accepted timestep by code instead of by secret, allowing a previously issued app-based MFA code to be accepted after a newer code has already been used. Reuse of the exact same code was already prevented, but another code inside the accepted time window remained usable. An attacker who obtains the target account's password and one app-based MFA code can use that code for the remainder of the configured window, which is approximately four minutes with the default settings, even after the legitimate account holder logs in with a newer code. Email-based MFA is not affected. This issue is fixed in versions 4.12.6 and 5.7.6.
