More details for your feedbacks: the application creates HTML pages, on URL basis, using templates.
The content aggregation logic is based on JSP. The application will retrieve these templates and, using TAGLIB technology, will substitute the TAGLIB with the dynamic content and metadata. The idea is to add the #include file tag in the new templates.
The contents and the templates come from company internal resources.
Thanks

Subject: Re: #include file tag in HTML: possible issues?
What type of code are we talking about ?
Not knowing what type of code is the application or stored in the
external file that gets inserted, it would be hard for anyone to think
of the threat scenarios, let alone the suggestions for remediation. If the external file's contents are checked against different types of
attacks that the particular code could possibly be vulnerable to, it
should be fine.
Moreover, who created these external files is a valid concern, since you
have not mentioned. If the external file's content is controlled that
could be another layer of security towards the final application. Regards Aman Raheja
