Detailsinfo

A vulnerability classified as critical has been found in Symfony up to 5.4.49/6.4.28/7.3.6. This affects the function Request. The manipulation of the argument PATH_INFO with an unknown input leads to a use of non-canonical url paths for authorization decisions vulnerability. CWE is classifying the issue as CWE-647. The product defines policy namespaces and makes authorization decisions based on the assumption that a URL is canonical. This can allow a non-canonical URL to bypass the authorization. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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 `/`.
