Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the lack of connection and header-read timeouts and the absence of a concurrent-connection cap in the default serve process. An attacker can exhaust server sockets and tasks by opening numerous connections and sending incomplete requests that are never finished.
