For a link-share token, the task query is correctly pinned to the share's own project, but the *view* is taken from the attacker-controlled path and never re-validated against the share.",

Para um token de compartilhamento de link, a consulta de tarefas é corretamente fixada no projeto próprio do compartilhamento, mas a *visualização* é obtida do caminho controlado pelo atacante e nunca revalidada contra o compartilhamento.",
