Incorrect authorization in Smart Polling configuration in Guardian/CMC before 26.3.0
An access control vulnerability was discovered in the Smart Polling configuration functionality due to insufficient validation of user privileges. An authenticated user with limited privileges can remotely bypass the intended access control of the web management interface and modify the Smart Polling discovery configuration. This allows the attacker to disrupt the visibility of assets in the monitored network.
