GHSA-mrqx-rp3w-jpjp
Symfony vulnerable to open redirect via browser-sanitized URLs
Quick fix
GHSA-mrqx-rp3w-jpjp — symfony/http-foundation: upgrade to the fixed version with the command below.
composer require symfony/http-foundation:^5.4.46Details
### Description
The `Request` class, does not parse URI with special characters the same way browsers do. As a result, an attacker can trick a validator relying on the `Request` class to redirect users to another domain.
### Resolution
The `Request::create` methods now assert the URI does not contain invalid characters as defined by https://url.spec.whatwg.org/
The patch for this issue is available [here](https://github.com/symfony/symfony/commit/5a9b08e5740af795854b1b639b7d45b9cbfe8819) for branch 5.4.
### Credits
We would like to thank Sam Mush - IPASSLab && ZGC Lab for reporting the issue and Nicolas Grekas for providing the fix.
