Script execution via unescaped model metadata
Published Aug 27, 2026 · Updated Aug 27, 2026
DOM-based XSS in Netron 9.1.2 and earlier allows attackers to execute JavaScript when a crafted model's node is selected. Netron writes model-supplied node names and input or output descriptions into sidebar innerHTML without escaping, causing embedded HTML to be parsed. A user must open the malicious model and select its node; the script can hide nodes or scan local services, while host RCE requires a separate Chromium flaw.
