CVE-2026-55065

Summary

Vikunja is an open-source self-hosted task management platform. From 0.24.6 until 2.4.0, DELETE /api/v1/projects/:project/views/:view permits an authenticated user to supply a view identifier from another project while authorizing only against an attacker-controlled project identifier. ProjectView.CanDelete in pkg/models/project_view_permissions.go does not establish that the view belongs to the path project, and ProjectView.Delete in pkg/models/project_view.go continues after the scoped project_views delete affects no rows. Its subsequent deletes select task_buckets and task_positions only by project_view_id, allowing cross-tenant destruction of Kanban assignments and ordering while leaving the victim view and tasks intact. This issue is fixed in version 2.4.0.
