Technical details
A server-side request forgery (SSRF) vulnerability in Microsoft Power Automate permits an authenticated attacker to send crafted requests that cause the service to make unintended network connections on the attacker's behalf. The vulnerability requires prior authentication and network access to Power Automate. Successful exploitation enables privilege escalation, allowing an attacker to access restricted resources or perform actions beyond their authorization level. Microsoft has published a security update to address this issue.
