Description

A vulnerability has been identified in Mendix Applications using Mendix 8 (All versions < V8.18.13), Mendix Applications using Mendix 9 (All versions < V9.6.2). Applications built with affected versions of Mendix Studio Pro do not properly control write access for certain client actions. This could allow authenticated attackers to manipulate the content of System.FileDocument objects in some cases, regardless whether they have write access to it.
