CVE-2026-105043: CWE-451 User Interface (UI) Misrepresentation of Critical Information in MathWorks Simulink
MathWorks Simulink versions before R2026b contain a vulnerability where crafted .slx files can include blocks that remain invisible in the Simulink Editor but trigger code execution. This issue is classified as a User Interface Misrepresentation of Critical Information (CWE-451). The vulnerability has a low CVSS score of 3.6 and requires local access with high attack complexity and user interaction.
AI Analysis
Technical Summary
CVE-2026-105043 describes a vulnerability in MathWorks Simulink prior to version R2026b. When opening a specially crafted .slx file, the software may contain blocks that are not visible in the Simulink Editor interface but can cause code execution. This represents a UI misrepresentation flaw (CWE-451) where critical information is hidden from the user, potentially misleading them about the file's true behavior. The CVSS 3.1 vector indicates local attack vector, high complexity, no privileges required, user interaction required, and low impact on confidentiality and integrity, with no availability impact.
Potential Impact
The vulnerability allows an attacker to execute code by exploiting invisible blocks in a crafted .slx file. However, exploitation requires local access, high attack complexity, and user interaction. The impact on confidentiality and integrity is low, and there is no impact on availability. There are no known exploits in the wild.
Mitigation Recommendations
No official patch or remediation information is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution when opening .slx files from untrusted sources and verify file authenticity.
