CVE-2026-17496
8.1 · HIGHOverview
CVE-2026-17496 is a high-severity vulnerability affecting notegen notegen. It was published on July 26, 2026 and has a CVSS 3.1 base score of 8.1 (HIGH).
This vulnerability has a CVSS 3.1 base score of 8.1, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
NoteGen before 0.32.0 renders AI chat responses with markdown-it configured with html:true and injects the result into the DOM via dangerouslySetInnerHTML in chat-preview, without HTML sanitization and with CSP set to null. Attacker-controlled content that reaches the model prompt (for example a malicious skill REFERENCE.md that instructs the model to emit HTML) can cause the model response to include executable markup such as an img onerror handler. When the user views the chat response, that markup runs as JavaScript in the privileged Tauri webview, enabling arbitrary script execution in the application context (cross-site scripting).
Remediation
Check the references section for vendor advisories and patches from notegen. Update notegen to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
