AI-suggested
A patch is available and should be applied by upgrading to Symfony HttpFoundation versions 5.4.46, 6.4.14, or 7.1.7 or later. The fix enforces strict URI validation according to the WHATWG URL specification, preventing the open redirect condition. Users should update to these fixed versions to mitigate the vulnerability.
Description
Symfony's HttpFoundation component contains an open redirect vulnerability (CVE-2024-50345) due to inconsistent URI parsing between the Request class and browsers. This allows attackers to bypass validators relying on the Request class and redirect users to unintended domains. The issue affects multiple versions prior to fixed releases. A patch is available that enforces URI validation against the WHATWG URL specification.
