AV:L because the attack requires opening a local file; S:C because Electron XSS crosses into the OS renderer context; C:H for port-scan capability; I:L for node-hiding display manipulation.

Reflected XSS in Netron versions <=9.1.2 on desktop application through unsanitized node names allows an attacker to hide certain nodes, perform port scanning or abuse a Chrome n-day to achieve Remote Code Execution.
AnalysisAI
Reflected XSS in Netron desktop application versions ≤9.1.2 executes attacker-controlled JavaScript when a victim opens a crafted neural network model file containing malicious node names, type labels, or value descriptions. Because Netron runs on Electron (a Chromium-based runtime), the injected script operates within a privileged renderer process capable of port-scanning local networks and, with a separately-acquired Chrome n-day, achieving full remote code execution on the host machine. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to open a malicious model file (e.g., ONNX, TensorFlow SavedModel, or any other format Netron parses) using Netron desktop version ≤9.1.2. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.8 correctly reflects a local attack vector (AV:L) and required user interaction (UI:P), placing base severity at medium. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts an ONNX or similar model file embedding a JavaScript payload within node name or value description fields and distributes it through a public model hub, a spear-phishing email, or a compromised internal model registry targeting ML researchers. When the victim opens the file in Netron ≤9.1.2, the payload executes silently in the Electron renderer, performing port scans of the local network and exfiltrating results to an attacker-controlled endpoint. … |
| Remediation | Upgrade Netron to any release incorporating commit cd14bad8c9132b1aaf1d197fe61925575f194f00, which is the first revision containing the complete fix; the exact patched release version number above 9.1.2 is not confirmed in the provided data, so users should verify the installed version includes this commit via the GitHub history at https://github.com/lutzroeder/netron/commit/cd14bad8c9132b1aaf1d197fe61925575f194f00. … Detailed patch versions, workarounds, and compensating controls in full report. |
