Prior to 3.4.1.15, TDengine Enterprise allowed an authenticated low-privilege SQL user to run KILL SSMIGRATE <id> against an active shared-storage migration because mndProcessKillSsMigrateReq called mndKillSsMigrate while the intended MND_OPER_SSMIGRATE_DB privilege check was commented out. This issue is fixed in version 3.4.1.15."

Antes de la versión 3.4.1.15, TDengine Enterprise permitía a un usuario SQL autenticado con bajos privilegios ejecutar KILL SSMIGRATE [id] contra una migración de almacenamiento compartido activa porque mndProcessKillSsMigrateReq llamaba a mndKillSsMigrate mientras que la comprobación de privilegios prevista MND_OPER_SSMIGRATE_DB estaba comentada. Este problema está solucionado en la versión 3.4.1.15."
