2th percentile - higher than 2% of all known CVEs

Summary

MathWorks Simulink before R2026b, when showing a crafted .slx file, can have blocks that are never visible in the Simulink Editor but will cause code execution.

Risk Assessment

Opening a crafted .slx file can lead to arbitrary code execution on the user's workstation. Because the malicious blocks are invisible in the editor, the user cannot detect them before opening the file.

Recommendation

Upgrade MathWorks Simulink to R2026b or later. Until then, avoid opening .slx files from untrusted sources.
