CVE-2026-34789: Freecad

High severity, CVSS 7.0. EPSS: 0.2% chance of exploitation in the next 30 days.

FreeCAD is a free and open-source multiplatform 3D parametric modeler. Prior to 1.1.2, src/App/PropertyPythonObject.cpp in PropertyPythonObject::Restore() passes the attacker-controlled module attribute from serialized PropertyPythonObject XML directly to PyImport_ImportModule() while restoring a crafted FCStd document, which executes module-level Python code, and the legacy pickle branch also imports an attacker-controlled module and invokes its class constructor through PyObject_CallObject(). This issue is fixed in version 1.1.2.

Affected products

• Freecad Freecad: before 1.1.2 (fixed in 1.1.2)
