CSP Frame Ancestors enabled by default

We just enabled the Content-Security-Policy (CSP) frame-ancestors directive by default on Discourse. By default it allows self and any domains allowed in Admin > Customize > Embedding. If necessary, a site administrator may disable it using the site setting content security policy frame ancestors, but that is not recommended.

您的主站是否已在“管理 > 自定义 > 嵌入”中注册？
