First, I'm using Emacs 27.2 and Org 9.4.6.
I have the following code in an Org file:
#+latex_header:
\hypersetup{pdfauthor={Author},pdftitle={Title},pdfsubject={Subject},pdfkeywords={keyword},pdfproducer={Emacs
Org},pdfcreator={pdflatex}}
#+latex_header: \hypersetup{colorlinks=true,urlcolor=blue,linkcolor=black}
The above lines are in a section at the end of my document.
When I do C-c C-x C-l in a section (or with a fragment at point), the following
appears above every fragment that is previewed:
pdfauthor=Author,pdftitle=Title,pdfsubject=Subject,pdfkeywords=keyword,pdfproducer=Emacs
Org,pdfcreator=pdflatex colorlinks=true,urlcolor=blue,linkcolor=black
Here is a sample section from my Org file:
--BEGIN--
* Distance Formula
Let $d$ be the distance between $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$.
\[
d=\sqrt{\left(x_{1}-x_{2}\right)^{2}+\left(y_{1}-y_{2}\right)^{2}}
\]
--END--
