CVE-2026-123503

Vikunja before 2.7.1 contains an improper authorization vulnerability in canDoBucket that allows users with project write access to delete buckets via a mismatched view ID. Attackers can request deletion through another view's bucket endpoint to bypass the last-bucket rule, leaving dangling default/done bucket references and inconsistent task buckets.
