CVE-2026-17496Public exploitNetwork attack vector

Script execution via unsanitized AI response HTML

Published Jul 26, 2026 · Updated Jul 26, 2026

Cross-site scripting in codexu NoteGen before 0.32.0 allows remote attackers to execute JavaScript through a crafted AI chat response. The chat-preview component enables HTML in markdown-it and passes rendered model output to dangerouslySetInnerHTML without sanitization while the Tauri CSP is disabled. Execution requires attacker-controlled prompt context, such as an installed malicious skill, and user interaction to view the response; resulting script runs in the privileged application webview.
