CVE-2026-34398: Freecad

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Freecad Freecad: from 0.19, before 1.1.1 (fixed in 1.1.1)
