FrankenPHP before 1.13.2 contains an uncontrolled recursion vulnerability in its PHP-to-Go array converter that fails to detect circular references in PHP arrays. Passing a self-referential array to frankenphp_log() or returning one from a worker callback triggers a fatal Go stack overflow, terminating the entire server process.
