When a read ends in the last bytes of a chunk, add() takes the chunk short and parses the leftover data as the next chunk-size line.\n\nA remote attacker can make a chunked body never complete, hanging a server that reads until the body is done, and may make it complete early, leaving the remaining bytes to be read as the next request."
