Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to missing memory accounting in HTTP/2 stream handling, where inbound data queued on an undrained stream is not charged to the session's memory budget, so maxSessionMemory neither bounds it nor refuses new streams. An attacker can exhaust server memory by filling a stream's receive window with one-byte data frames, which costs about 10 wire bytes per frame while the server retains about 114 bytes per frame. Only servers that serve HTTP/2 and leave a stream's incoming data unread are affected.
