  "details": "Podgrab contains an unauthenticated denial-of-service vulnerability caused by unsynchronized concurrent access to shared maps (activePlayers and allConnections) in its WebSocket handler, where Wshandler and HandleWebsocketMessages goroutines read and write these maps without a mutex. A remote attacker can open multiple WebSocket connections to the /ws endpoint and send messages in a loop to trigger a Go runtime data race that crashes the process, causing a denial of service that requires operator intervention to restore service.",
