- WordPress 4.7正式版本发布及中文网站如何升级
如果我们用户有在使用WordPress程序的应该在昨天看到后台有升级提示，晚些时候更新中文版本，其实不论我们中文版本还是英文版本，对于升级后语言是没有影响的。这次中文版本跟进速度较快，可以看到其应该是有安全更新的，从官方的文档可以看到更新8个重要安全问题。
官方文档：https://codex.wordpress.org/Version_4.7.1
具体如下：
1、Remote code execution (RCE) in PHPMailer – No specific issue appears to affect WordPress or any of the major plugins we investigated but, out of an abundance of caution, we updated PHPMailer in this release.
2、The REST API exposed user data for all users who had authored a post of a public post type. WordPress 4.7.1 limits this to only post types which have specified that they should be shown within the REST API.
3、Cross-site scripting (XSS) via the plugin name or version header on update-core.php.
4、Cross-site request forgery (CSRF) bypass via uploading a Flash file.
5、Cross-site scripting (XSS) via theme name fallback.
6、Post via email checks mail.example.com if default settings aren't changed.
7、A cross-site request forgery (CSRF) was discovered in the accessibility mode of widget editing.
8、Weak cryptographic security for multisite activation key.
与此同时，还更新和升级上一个版本以来的多个BUG问题。老蒋个人建议用户还是尽快升级，参考"WordPress程序自动与手动升级新版本的操作过程"。
