Access restriction bypass |
|
| Description |
| + |
Support for a (legacy) IIS header that lets users override the path in the request URL via the X-Original-URL or X-Rewrite-URL HTTP request header allows a user to access one URL but have Symfony return a different one which can bypass restrictions on higher level caches and web servers. |

|
| + |
The fix drops support for these two obsolete IIS headers: X-Original-URL and X_REWRITE_URL. |
