CVE-2024-50345: Sensiolabs Symfony

Medium severity, CVSS 6.1. EPSS: 0.6% chance of exploitation in the next 30 days.

symfony/http-foundation is a module for the Symphony PHP framework which defines an object-oriented layer for the HTTP specification. 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. The `Request::create` methods now assert the URI does not contain invalid characters as defined by https://url.spec.whatwg.org/. This issue has been patched in versions 5.4.46, 6.4.14, and 7.1.7. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Affected products

• Sensiolabs Symfony: before 5.4.46 (fixed in 5.4.46); from 6.0.0, before 6.4.14 (fixed in 6.4.14); from 7.0.0, before 7.1.7 (fixed in 7.1.7)
