Consider including the charset in the content type header (e.g., application/xml; charset=UTF-8) to ensure correct encoding handling by clients.

Unescaped variables in the XML output can lead to malformed XML or injection attacks if values contain special characters (&, <, >). Apply proper XML escaping for each inserted variable.

⚠️ Potential issue

Mitigate XML injection / parsing errors by escaping special characters.

Interpolated variables like $http_user_agent may contain &, <, > or other characters that break XML or introduce injection risks. Wrap user-supplied fields in CDATA sections or apply proper escaping. For example:

-  <user_agent>$http_user_agent</user_agent>
+  <user_agent><![CDATA[$http_user_agent]]></user_agent>

Additionally, consider wrapping other fields (e.g., <country_name>, <as_desc>) in CDATA if they originate from external data.

🤖 Prompt for AI Agents 
In nginx/conf.d/ipinfo.conf around lines 65 to 66, the XML response includes
interpolated variables such as $http_user_agent, $country_name, and $as_desc
that may contain special characters causing XML injection or parsing errors. To
fix this, wrap these variable values inside CDATA sections to safely include any
special characters without breaking the XML structure. Update the XML tags for
user_agent, country_name, and as_desc to enclose their values within <![CDATA[
and ]]>, ensuring the XML remains well-formed and secure.
