Vulnerability Title
FreeCAD: Arbitrary Code Execution via eval() on untrusted project file metadata in BIM Workbench
Source: CVE Program / CVE List V5
Vulnerability Description
FreeCAD is a free and open-source multiplatform 3D parametric modeler. From 0.19 until 1.1.1, src/Mod/BIM/bimcommands/BimProjectManager.py in the BIM Project Manager Load Template flow passes attacker-controlled FCStd Meta property values for wpposition, wpu, wpv, and wpaxis directly to eval(), allowing arbitrary Python code execution when a user loads a malicious BIM project template. This issue is fixed in version 1.1.1.

Vulnerability Title
FreeCAD 代码注入漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
FreeCAD是FreeCAD组织的一款三维参数化计算机辅助设计软件。 FreeCAD 0.19至1.1.1之前版本存在代码注入漏洞，该漏洞源于BIM Project Manager Load Template流程中的src/Mod/BIM/bimcommands/BimProjectManager.py文件将攻击者控制的FCStd Meta属性值wpposition、wpu、wpv和wpaxis直接传递给eval()函数，可能导致任意Python代码执行。
