Every CVE for FreeCAD

Exploited in the last 30 days

FreeCAD is a free and open-source multiplatform 3D parametric modeler. Prior to 1.1.2, the FEM Displacement Constraint task dialog in src/Mod/Fem/Gui/TaskFemConstraintDisplacement.cpp passes the xDisplacementFormula, yDisplacementFormula, and zDisplacementFormula fields of a Fem::ConstraintDisplacement object through TaskDlgFemConstraintDisplacement::accept() into Gui::Command::doCommand. The escaping helper neutralizes quotation marks but not backslashes, allowing crafted formula text to terminate the generated Python string and execute arbitrary Python code with the FreeCAD process's privileges when a victim accepts the dialog. This issue is fixed in version 1.1.2.
