修复主题和插件静态资源的文件遍历漏洞
漏洞描述：
攻击者可以通过`/plugins/{name}/assets/console/{*resource}` 和 `/themes/{themeName}/assets/{*resource}` 的 resource 参数部分添加特殊字符（如 ../ 或 ..\）来绕过应用程序的访问控制，访问他们没有权限访问的文件或目录。
修复方法：
访问文件之前检查文件路径是否在被限制的目录下，如:
resource = /themes/default/templates/../../test
简化路径为 /themes/test
想限制路径在 `/themes/default/templates` 则已经越权拒绝访问
how to test it?
1. 访问例如 `localhost:8090/themes/theme-earth/assets/dist/../../../../../keys/id_rsa` 来检查获取上级目录，上上级目录是否可以访问到，必须只能访问到 themes/assets下的文件即为合理
2. 类似步骤 1 可以尝试`../`， `..\` 来访问 `localhost:8090/plugins/{name}/assets/console/{*resource}`，必须只能访问到插件的 `classpath:console/` 下的文件即为合理
