CVE-2026-73234— FreeCAD: FCStd path traversal allows arbitrary file write via unsanitized file attribute in PropertyFileIncluded::Restore()

Quick assessment

Affected
FreeCAD FreeCAD
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

FreeCAD是FreeCAD组织的一款参数化三维计算机辅助设计软件。 FreeCAD 1.1.2之前版本存在路径遍历漏洞，该漏洞源于PropertyFileIncluded::Restore()函数在拼接Document.xml中的文件或数据属性时未拒绝目录组件、绝对路径或父目录遍历，攻击者可通过特制的.FcStd存档将内容写入任意位置，可能导致持久化、凭据泄露、配置替换或代码执行。

Vulnerability Title
FreeCAD: FCStd path traversal allows arbitrary file write via unsanitized file attribute in PropertyFileIncluded::Restore()
Source: CVE Program / CVE List V5
Vulnerability Description
FreeCAD is a free and open-source multiplatform 3D parametric modeler. Prior to 1.1.2, PropertyFileIncluded::Restore() in src/App/PropertyFile.cpp concatenates an attacker-controlled file or data attribute from Document.xml with the document transient path without rejecting directory components, absolute paths, or parent traversal. A crafted .FCStd archive with a matching FileIncluded XML attribute and ZIP entry can therefore write attacker-controlled content to arbitrary locations accessible to the FreeCAD user, potentially enabling persistence, credential compromise, configuration replacement, or code execution. This issue is fixed in version 1.1.2.
