Vikunja has a Link Share Delete IDOR — Missing Project Ownership Check Allows Cross-Project Link Share Deletion
CVE-2026-33700
Description
Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, the DELETE /api/v1/projects/:project/shares/:share endpoint does not verify that the link share belongs to the project specified in the URL. An attacker with admin access to any project can delete link shares from other projects by providing their own project ID combined with the target share ID. Version 2.2.1 patches the issue.
