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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.0},"cwes":["CWE-94"],"references":["https://github.com/FreeCAD/FreeCAD/commit/81b73925ce22610542367301d8eff4259eb9596e","https://github.com/FreeCAD/FreeCAD/commit/983037f3003dc31f48db36705b86fb3fbe026295","https://github.com/FreeCAD/FreeCAD/commit/e2dc6c8172673642c6856b8b3a5a6accefb18279","https://github.com/FreeCAD/FreeCAD/releases/tag/1.1.2","https://github.com/FreeCAD/FreeCAD/security/advisories/GHSA-493w-pp4h-h77v"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-34789","score":0.00196,"percentile":0.09324,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
