Vikunja Desktop: Any frontend XSS escalates to Remote Code Execution due to nodeIntegration

Assigner: GitHub_M
Reserved: 18.03.2026 Published: 24.03.2026 Updated: 24.03.2026

Vikunja is an open-source self-hosted task management platform. Starting in version 0.21.0 and prior to version 2.2.0, the Vikunja Desktop Electron wrapper enables nodeIntegration in the renderer process without contextIsolation or sandbox. This means any cross-site scripting (XSS) vulnerability in the Vikunja web frontend -- present or future -- automatically escalates to full remote code execution on the victim's machine, as injected scripts gain access to Node.js APIs. Version 2.2.0 fixes the issue.
