Machine-written summary

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

Filament (Packagist package filament/filament) versions 4.0.0 up to 4.11.5 and 5.0.0 up to 5.6.5 have a timing discrepancy on the login page that lets unauthenticated attackers determine whether a given email address is registered. The impact is limited to disclosing account existence, and the source gives few further details about how the timing difference is measured. Upgrade to version 4.11.5 or 5.6.5, depending on the release line in use.
