Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via Application.__handle_recv(). An attacker can exhaust server memory or CPU resources by causing the system to process unbounded TCP response data from an attacker-controlled upstream server. This is achieved by sending excessively large or continuous response chunks, leading to excessive memory allocation and CPU usage until the connection times out. Multiple concurrent requests can also overflow the accept queue, preventing legitimate clients from connecting.
