On a miss it keeps everything and searches again from the start when the next chunk arrives. A body with no boundary, or with a delimiter followed by neither CRLF nor \"--\", is therefore rescanned on every chunk, taking time quadratic in its size.\n\nA remote attacker can exhaust worker CPU with a few such requests."
