Name of the Vulnerable Software and Affected Versions
Centrifugo versions prior to 6.8.4
Description
Unauthenticated requests to the '/connection/uni websocket' endpoint can cause excessive memory and CPU consumption. This occurs when the unidirectional WebSocket transport has
uni websocket.compression enabled; while the uni websocket.message size limit is enforced against the compressed wire-frame length in the advanceFrame() function, the ReadMessage() function uses io.ReadAll after decompression without an output cap.Recommendations
Update to version 6.8.4.
