Prior to 1.1.2, src/App/PropertyPythonObject.cpp in PropertyPythonObject::Restore() passes the attacker-controlled module attribute from serialized PropertyPythonObject XML directly to PyImport_ImportModule() while restoring a crafted FCStd document, which executes module-level Python code, and the legacy pickle branch also imports an attacker-controlled module and invokes its class constructor through PyObject_CallObject(). This issue is fixed in version 1.1.2.","published":"2026-08-17T21:16:44.403","modified":"2026-08-17T21:16:44.403","cvss":{"score":7,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/FreeCAD/FreeCAD/commit/81b73925ce22610542367301d8eff4259eb9596e","label":"FreeCAD/FreeCAD@81b7392"},"references":[{"type":"WEB","url":"https://github.com/FreeCAD/FreeCAD/commit/81b73925ce22610542367301d8eff4259eb9596e"},{"type":"WEB","url":"https://github.com/FreeCAD/FreeCAD/commit/983037f3003dc31f48db36705b86fb3fbe026295"},{"type":"WEB","url":"https://github.com/FreeCAD/FreeCAD/commit/e2dc6c8172673642c6856b8b3a5a6accefb18279"},{"type":"WEB","url":"https://github.com/FreeCAD/FreeCAD/releases/tag/1.1.2"},{"type":"WEB","url":"https://github.com/FreeCAD/FreeCAD/security/advisories/GHSA-493w-pp4h-h77v"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-17T21:16:44.403"}}
