Prior to 9.9.1-alpha.12 and 8.6.82, deeply nested $or, $and, and $nor query condition operators in the REST API or LiveQuery query handling could trigger exponential-time processing in the internal query-traversal helper and block the Node.js event loop. This issue is fixed in versions 9.9.1-alpha.12 and 8.6.82."

Antes de las versiones 9.9.1-alpha.12 y 8.6.82, los operadores de condición de consulta $or, $and y $nor profundamente anidados en el manejo de consultas de la API REST o LiveQuery podían desencadenar un procesamiento de tiempo exponencial en el ayudante interno de recorrido de consultas y bloquear el bucle de eventos de Node.js. Este problema está solucionado en las versiones 9.9.1-alpha.12 y 8.6.82."
