Filament: Timing-based user enumeration on login page

Published Jun 22, 2026 · Updated Jun 23, 2026 · Assigned by GitHub_M

Description

Filament is a collection of full-stack components for accelerated Laravel development. From 4.0.0 until 4.11.5 and 5.6.5, the login page has an observable timing discrepancy that allows unauthenticated attackers to enumerate registered email addresses. The impact is limited to disclosing whether an account exists for a given email. This vulnerability is fixed in 4.11.5 and 5.6.5.
