What is CVE-2021-42025?

A significant vulnerability has been identified in Mendix Applications built on versions of Mendix Studio Pro prior to V8.18.13 and V9.6.2. This issue arises from insufficient control over write access for certain client actions, allowing authenticated attackers to manipulate System.FileDocument objects.
