CVE-2026-56146

Improper Access Control (CWE-284) in Kibana can lead to unauthorized modification of Entity Analytics Watchlist configuration and potential information disclosure. A low-privileged authenticated user with read-only Security Solution access could perform write operations on watchlist data that should require elevated privileges. Under specific deployment conditions, this could also allow such a user to access data beyond their authorized scope.

Summary		(es) Un Control de Acceso Inadecuado (CWE-284) en Kibana puede llevar a la modificación no autorizada de la configuración de la lista de seguimiento de Entity Analytics y a una posible revelación de información. Un usuario autenticado con privilegios bajos y acceso de solo lectura a Security Solution podría realizar operaciones de escritura en los datos de la lista de seguimiento que deberían requerir privilegios elevados. Bajo condiciones de despliegue específicas, esto también podría permitir a dicho usuario acceder a datos más allá de su alcance autorizado.
