FKIE_CVE-2026-73235

Vulnerability from fkie_nvd - Published: 2026-08-11 20:18 - Updated: 2026-08-12 23:17
Severity
6.1 (Medium) - CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N
Summary
FreeCAD is a free and open-source multiplatform 3D parametric modeler. Prior to 1.1.2, the Xerces SAX2 XMLReader constructed in src/Base/Reader.cpp by Base::XMLReader::XMLReader() parses attacker-controlled Document.xml from a crafted .FCStd archive without disabling default external entity resolution or external DTD loading. When Document::restore() opens the document, external entities can read local files through the file URI scheme or initiate server-side requests through the http URI scheme, and resolved content can flow through the characters() callback. This issue is fixed in version 1.1.2.
