urllib3: HTTPResponse.stream()/read_chunked() buffers an unbounded chunk-size line into memory

Impacturllib3's streaming API is designed for efficiently handling large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. When decoding a chunked-transfer-encoded response, this API reads each chunk's size field by buffering until ...

sanic chunked trailer request smuggling allows hidden second request execution

DescriptionSanic's HTTP/1.1 chunked-body handling does not fully consume the trailer-part after the terminating 0\r\n chunk. Because of that, attacker-controlled bytes left in the connection buffer after the first chunked request can be interpreted as the start of a new HTTP request on the same...
