CVE-2026-73233
FreeCAD dialog permits code injection via displacement formulas, enabling arbitrary Python execution.
Is CVE-2026-73233 being exploited?
Not confirmed. CVE-2026-73233 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly.

How severe is CVE-2026-73233?
CVE-2026-73233 is rated High. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2026-73233?

What does CVE-2026-73233 affect?
CVE-2026-73233 affects FreeCAD versions prior to 1.1.2 (FEM TaskFemConstraintDisplacement). Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-73233?
Upgrade FreeCAD to 1.1.2+ and avoid opening untrusted FEM files.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Arbitrary Python code execution in the FreeCAD process when a user accepts a crafted FEM displacement dialog; can run commands and access files.
Immediate action required

As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
