CVE-2025-64500
Good to know:
Date: November 12, 2025
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Symfony's HttpFoundation component defines an object-oriented layer for the HTTP specification. Starting in version 2.0.0 and prior to version 5.4.50, 6.4.29, and 7.3.7, the "Request" class improperly interprets some "PATH_INFO" in a way that leads to representing some URLs with a path that doesn't start with a "/". This can allow bypassing some access control rules that are built with this "/"-prefix assumption. Starting in versions 5.4.50, 6.4.29, and 7.3.7, the "Request" class now ensures that URL paths always start with a "/".
