- CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
Description
### Description 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. ### Resolution The `Request` class now ensures that URL paths always start with a `/`. The patch for this issue is available [here](https://github.com/symfony/symfony/commit/9962b91b12bb791322fa73836b350836b6db7cac) for branch 5.4. ### Credits We would like to thank Andrew Atkinson for discovering the issue, Chris Smith for reporting it and Nicolas Grekas for providing the fix.
