CVE-2026-81892 (opens in a new tab)How to fix?
Upgrade easycorp/easyadmin-bundle to version 4.29.16, 5.5.1 or higher.
Overview
Affected versions of this package are vulnerable to Incorrect Authorization via the routeName query parameter in the custom-action dispatch process. An attacker can gain unauthorized access to restricted backend routes by specifying the name of a protected route, thereby bypassing path-based access controls. This is only exploitable if the application relies solely on path-based access control rules and does not enforce controller-level authorization.
Workaround
This vulnerability can be mitigated by adding controller-level authorization checks (such as #[IsGranted] or denyAccessUnlessGranted()) to sensitive routes.
