CVE-2026-123494 Details
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.
A cross-site request forgery (CSRF) vulnerability has been identified in Vikunja versions prior to 2.7.1. This vulnerability allows attackers to import data into a victim's account through the Todoist, Microsoft To Do, and Trello migration OAuth callbacks, which lack a bound state parameter. Attackers can authorize their own accounts, retain the unused callback code or token, and entice a logged-in victim to the migration callback route. This action triggers an automatic import of projects and tasks selected by the attacker, which can include phishing links.
Users can upgrade to Vikunja version 2.7.1 or later to address this vulnerability.
