DescriptionCVE.org
FrankenPHP before 1.13.4 contains a denial of service vulnerability in worker mode where frankenphp_handle_request() returns false without finishing the dequeued request after a fatal error during request startup. Attackers who trigger startup fatal errors against worker scripts that keep calling frankenphp_handle_request() can leave client requests hanging indefinitely while the worker continues running.
