CVE-2026-73235Public exploit

File read and SSRF via unhardened XML parser

Published Aug 11, 2026 · Updated Aug 11, 2026

XXE in FreeCAD before 1.1.2 allows attackers to read local files or issue HTTP requests when a user opens a crafted .FCStd file. The SAX2 XMLReader in src/Base/Reader.cpp parses Document.xml without disabling external entity resolution or external DTD loading. Opening the archive is required; resolved file content can reach the parser callback, while HTTP entities can contact services reachable from the workstation.
