org.eclipse.jetty.websocket/websocket-core-common: Jetty: Denial of Service via crafted WebSocket frame with unknown opcode
A client may send a WebSocket frame with an unknown opcode and a very large declared payload length, causing Jetty to attempt a large memory allocation and potentially exhaust the JVM heap. This occurs when auto-fragmentation is enabled, as unknown opcodes bypass the normal maximum frame size handling and payload allocation occurs before the opcode is validated.
