GHSA-X424-64QH-5J54 react/http: A malformed HTTP chunked body can lead to a denial-of-service and peg the CPU

Summary A malformed HTTP message using Transfer-Encoding: chunked can drive React\Http\Io\ChunkedDecoder into an infinite loop, pegging a CPU core and freezing the event loop. Because ReactPHP is single-threaded, one such message stalls the entire process for every client until it is killed. Both...
