CVE-2026-33334: Vikunja

Critical severity, CVSS 9.6. EPSS: 0.7% chance of exploitation in the next 30 days.

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.

Affected products

• Vikunja Vikunja: from 0.21.0, before 2.2.2 (fixed in 2.2.2)
