Overview
Affected versions of this package are vulnerable to Infinite loop through the multipart MIME body parsing process. An attacker can cause worker processes to enter an infinite loop and consume 100% CPU by sending a specially crafted multipart/form-data request with a partial closing boundary, leading to server unavailability until manual intervention.
