Technical details
The vulnerability stems from improper input validation in Power BI that fails to sanitize user-supplied data before processing. An authenticated attacker can craft malicious input to trigger code execution through a network-accessible interface. The attack requires valid credentials (authorized attacker), but once exploited allows remote code execution with the privileges of the Power BI service. Patches should be available from Microsoft through their standard update mechanisms.
