+Understanding the security implications of documentation pages
+==============================================================
+
+This article explains the security implications of documentation pages,
+this doesn't apply to the main dashboard (readthedocs.org/readthedocs.com),
+only to documentation pages (readthedocs.io, readthedocs-hosted.com, and custom domains).
+
+.. seealso::
+
+   :doc:`/api/cross-site-requests`
+      Learn about cross-origin requests in our public APIs.
+
+Cross-origin requests
+---------------------
+
+Read the Docs allows `cross-origin requests`_ for documentation resources it serves.
+However, internal and proxied APIs, typically found under the ``/_/`` path don't allow cross-origin requests.
+
+To facilitate this, the following headers are added to all responses from documentation pages:
+
+- ``Access-Control-Allow-Origin: *``
+- ``Access-Control-Allow-Methods: GET, HEAD, OPTIONS``
+
+These headers allow cross-origin requests from any origin
+and only allow the GET, HEAD and OPTIONS methods.
+It's important to note that passing credentials (such as cookies or HTTP authentication)
+in cross-origin requests is not allowed,
+ensuring access to public resources only.
+
+Having cross-origin requests enabled allows third-party websites to make use of files from your documentation (as long as they are public),
+which allows various third-party integrations to work.
+
+If needed, the ``Access-Control`` headers can be changed for your documentation pages by :doc:`contacting support </support>`.
+**You are responsible for providing the correct values for these headers, and making sure they don't break your documentation pages.**

+
+Cookies
+-------
+
+On |org_brand|, we don't use cookies, as all resources are public.
+
+On |com_brand|, we use cookies to store user sessions.
+These cookies are set when a user authenticates to access private documentation.
+Session cookies have the ``SameSite`` attribute set to ``None``,
+which allows them to be sent in cross-origin requests where allowed
+(see :ref:`security-implications:Cross-origin requests`),
+for example, when embedding private documentation pages in an iframe
+(see :ref:`security-implications:Embedding documentation pages`).
+
+Embedding documentation pages
+-----------------------------
+
+Embedding documentation pages in an iframe is allowed.
+Read the Docs doesn't set the ``X-Frame-Options`` or ``Content-Security-Policy`` headers,
+which means that the browser's default behavior is used.
+
+Embedding private documentation pages in an iframe is possible,
+but it requires users to be previously authenticated in the embedded domain.
+
+It's important to note that embedding documentation pages in an iframe does not grant the parent page access the iframe's content.
+Documentation pages serve static content only, and the exposed APIs are read-only,
+making the exploitation of a clickjacking vulnerability very unlikely.
+
+If needed, the ``X-Frame-Options`` and ``Content-Security-Policy`` headers can be set on your documentation pages by :doc:`contacting support </support>`.
+**You are responsible for providing the correct values for these headers, and making sure they don't break your documentation pages.**
