What is CVE-2026-25935?

The Vikunja Todo-App is susceptible to an XSS vulnerability, where a malicious user can exploit the application by creating a project with a harmful task. This occurs because the app temporarily generates a div element and assigns it innerHTML without proper escaping on the server or client sides. When another user hovers over this task, the malicious script can execute, potentially compromising user data and application integrity. This issue was addressed and fixed in version 1.1.0.

Affected Version(s)

vikunja < 1.1.0
