Vikunja 0.13.0 before 2.7.0 contains an incorrect authorization vulnerability that allows project members with Write permission to delete admin-tier link shares because the delete permission check reads an unloaded share object. Attackers can send DELETE requests to the v1 or v2 projects shares endpoints with sequential share IDs to revoke admin links and invalidate existing share sessions.
