  "details": "FreeCAD is a free and open-source multiplatform 3D parametric modeler. From 0.19 until 1.1.1, FreeCAD's BIM Workbench contains an eval() call on untrusted data from SVG template files. When a user creates a TechDraw page from a malicious SVG template, arbitrary Python code executes. The vulnerable code is in src/Mod/BIM/bimcommands/BimTDPage.py (line 87). This issue is fixed in version 1.1.1.",
