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.","published":"2026-08-11T20:18:48.693","modified":"2026-08-11T20:18:48.693","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/FreeCAD/FreeCAD/commit/0a208ac11cfe7b61c424ee4bb79117138ec50ac2","label":"FreeCAD/FreeCAD@0a208ac"},"references":[{"type":"WEB","url":"https://github.com/FreeCAD/FreeCAD/commit/0a208ac11cfe7b61c424ee4bb79117138ec50ac2"},{"type":"WEB","url":"https://github.com/FreeCAD/FreeCAD/commit/3f60d202a8246958232e2fbc74ba38a83483b74e"},{"type":"WEB","url":"https://github.com/FreeCAD/FreeCAD/pull/31267"},{"type":"WEB","url":"https://github.com/FreeCAD/FreeCAD/pull/31312"},{"type":"WEB","url":"https://github.com/FreeCAD/FreeCAD/releases/tag/1.1.2"},{"type":"WEB","url":"https://github.com/FreeCAD/FreeCAD/security/advisories/GHSA-2rq3-gx3h-489q"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-11T20:18:48.693"}}
