What is CVE-2026-17496?

NoteGen versions prior to 0.32.0 contain a vulnerability where AI chat responses are rendered using markdown-it with html:true, exposing the application to potential Cross-Site Scripting (XSS) attacks. Due to the lack of HTML sanitization and a null Content Security Policy (CSP), an attacker could inject malicious HTML into chat responses. This allows for the execution of arbitrary JavaScript in the trusted environment of the Tauri webview when users view these responses, potentially compromising user data and the integrity of the application.

Affected Version(s)

NoteGen 0 < 0.32.0
