Official Description
CMDBuild 3.3.2 contains multiple stored cross-site scripting vulnerabilities that allow authenticated attackers to inject arbitrary web script or HTML via crafted input in card creation and file upload endpoints.

Technical Analysis
CVE-2021-47925 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
