Name of the Vulnerable Software and Affected Versions quarkus-websockets-next (affected versions not specified)
Description A flaw allows a remote attacker to cause a Denial of Service (DoS) by streaming messages over a single connection faster than the application can process them. This occurs due to unbounded message buffering and a lack of read backpressure, which rapidly exhausts heap space and leads to a java.lang.OutOfMemoryError, crashing the Java Virtual Machine (JVM).
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
