  "summary": "CVE-2026-34789 is fixed in 2 products on 2 platforms, first by FreeCAD 1.1.2, released July 23, 2026. It is not reported as exploited. Patch Radar priority: High.",
  "title": "FreeCAD: Arbitrary code execution via unsandboxed PyImport_ImportModule in PropertyPythonObject::Restore",
  "description": "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.",
