CVE-2026-79720Hinoki check available

Script execution via unescaped sidebar model fields

Published Aug 27, 2026 · Updated Aug 27, 2026

Cross-site scripting in Lutz Roeder Netron 9.1.2 and earlier allows attackers to execute script when a crafted model file is opened. NodeView.expand and related sidebar views assign unescaped node names and value descriptions to innerHTML, causing Chromium to parse attacker-supplied markup. A user must open the model and select its malicious node; injected frames can hide graph content or probe local services, while host code execution additionally requires a Chromium renderer exploit.
