What is CVE-2026-33336?

Vikunja, an open-source self-hosted task management tool, has a vulnerability that allows attackers to exploit a misconfiguration in the Desktop Electron wrapper. The nodeIntegration setting, when enabled, grants full access to Node.js APIs within the browser context. Without proper navigation handlers, attackers can craft user-generated content containing malicious links. When a victim interacts with this content, the application navigates to the attacker-controlled site, leading to arbitrary code execution on the victim's system. Vikunja version 2.2.0 addresses this serious security flaw.

Affected Version(s)

vikunja >= 0.21.0, < 2.2.0
