The opening handshake is now aborted if the client receives a
Sec-WebSocket-Extensions header but no extension was requested or if the
server indicates an extension not requested by the client (aca94c86).
7.5.1
Bug fixes
Fixed an issue that prevented the connection from being closed properly if an
error occurred simultaneously on both peers (b434b9f1).
7.5.0
Features
Some errors now have a code property describing the specific type of error
that has occurred (#1901).
Bug fixes
A close frame is now sent to the remote peer if an error (such as a data
framing error) occurs (8806aa9a).
The close code is now always 1006 if no close frame is received, even if the
connection is closed due to an error (8806aa9a).
7.4.6
Bug fixes
Fixed a ReDoS vulnerability (00c425ec).
A specially crafted value of the Sec-Websocket-Protocol header could be used
to significantly slow down a ws server.
for (const length of [1000, 2000, 4000, 8000, 16000, 32000]) {
const value = 'b' + ' '.repeat(length) + 'x';
const start = process.hrtime.bigint();
value.trim().split(/ *, */);
const end = process.hrtime.bigint();
console.log('length = %d, time = %f ns', length, end - start);
}
The vulnerability was responsibly disclosed along with a fix in private by
Robert McLaughlin from University of California, Santa Barbara.
