Executive Summary

CVE-2026-79718 is a reflected Cross-Site Scripting (XSS) vulnerability in Netron versions 9.1.2 and earlier. It occurs because Netron renders user-controlled model fields without proper HTML escaping. An attacker can inject arbitrary HTML into the Netron sidebar by crafting a malicious model file, which is then rendered when a user interacts with the application.

Detection Guidance

To detect this vulnerability, check the installed Netron version on your system. If it is version 9.1.2 or earlier, the system is vulnerable. Run commands like 'netron --version' or check the application's about section. Inspect model files for unsanitized HTML strings in node names or descriptions.

Impact Analysis

This vulnerability allows an attacker to hide certain nodes, perform port scanning, or chain it with known V8 renderer n-day vulnerabilities in the embedded Chromium version to achieve Remote Code Execution (RCE) on the host system. While Netron may not handle sensitive data like cookies, the potential for RCE poses a significant risk.

Mitigation Strategies

Immediately update Netron to version 9.1.3 or later. If updating is not possible, avoid opening untrusted model files in Netron. Disable the use of external frames by ensuring CSP settings include 'frame-src none'. Monitor for suspicious activity like hidden nodes or unexpected network connections.
