Summary
FreeCAD is a free and open-source multiplatform 3D parametric modeler. Prior to 1.1.2, PropertyFileIncluded::Restore() in src/App/PropertyFile.cpp concatenates an attacker-controlled file or data attribute from Document.xml with the document transient path without rejecting directory components, absolute paths, or parent traversal. A crafted .FCStd archive with a matching FileIncluded XML attribute and ZIP entry can therefore write attacker-controlled content to arbitrary locations accessible to the FreeCAD user, potentially enabling persistence, credential compromise, configuration replacement, or code execution. This issue is fixed in version 1.1.2.
