Duplicate Advisory: Vikunja: Cross-tenant task-position rows can be injected into arbitrary project views via the unvalidated project_view_id in the task position endpoint (v1 and v2)

Published Sep 15, 2026·Updated Oct 9, 2026

NVD Description

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-w39f-h553-h2mx. This link is maintained to preserve external references. ### Original Description Vikunja before 2.6.0 fails to validate that user-supplied project_view_id in task-position requests belongs to the task's project. Authenticated attackers can insert task position rows into arbitrary other tenant project views via POST or PUT task-position endpoints.
