CVE-2026-123494

LowCVSS 3.5/10Last modified Nov 9, 2026

Description

Vikunja before 2.7.1 contains a cross-site request forgery vulnerability that allows attackers to import their data into a victim's account because the Todoist, Microsoft To Do, and Trello migration OAuth callbacks lack a bound state parameter. Attackers can authorize their own account, keep the unused callback code or token, and lure a logged-in victim to the migration callback route to auto-import attacker-chosen projects and tasks containing phishing links.
