NewCVE-2026-45075 (opens in a new tab)How to fix?
Upgrade symfony/http-kernel to version 7.4.12, 8.0.12 or higher.
Overview
symfony/http-kernel is a Symfony component that provides a structured process for converting a Request into a Response.
Affected versions of this package are vulnerable to Incorrect Authorization in the router due to the improper enforcement of IsGranted, IsSignatureValid, and IsCsrfTokenValid attributes checks across HTTP methods. An attacker can bypass these authorization attributes set for GET method with HEAD request to exfiltrate content or in some cases alter the data in the DB.
