Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada streetwriters notesnook desktop. Skor CVSS 3.1 8.6 (High) menurut github.com.

Deskripsi (NVD)

Notesnook is a note-taking app. Prior to version 3.3.11 on Web/Desktop, a cross-site scripting vulnerability stored in the note history comparison viewer can escalate to remote code execution in a desktop application. The issue is triggered when an attacker-controlled note header is displayed using `dangerouslySetInnerHTML` without secure handling. When combined with the full backup and restore feature in the desktop application, this becomes remote code execution because Electron is configured with `nodeIntegration: true` and `contextIsolation: false`. Version 3.3.11 patches the issue.
