是形式目标＝“_自我；易受攻击

我有一个困惑，我正在浏览一个博客，在它的评论中，有人建议target="_self"易受攻击。这是真的，如果是的话，我们该怎么解决？

<form action="../process.php" method="post" name="login-form" target="_self">
    <div class="FormItem">Username:
      <span id="sprytextfield1">
      <input class="textbox" type="text" name="text1" id="text1">
      <span class="textfieldRequiredMsg">A value is required.</span></span>
      </div>
      <div class="clear"></div>
      <div class="FormItem">Password:
        <span id="sprypassword1">
        <input class="textbox" type="password" name="password" id="password1">
      <span class="passwordRequiredMsg">A value is required.</span></span>
      </div>
      <div class="FormItem">
      <input name="login-submit" type="submit" value="SUBMIT">
      </div>
    </form>
