Org version is 9.5.2; emacs version is 27.1.
The manual does not indicate that underscores need to be escaped in
links (and they can't be, as far as I can tell). The latex and html
exporters interpret them as the start of a subscript.

#+AUTHOR: Leo Butler
#+TITLE: Bug in processing underscores in links
#+OPTIONS: toc:nil num:nil
* Description
The link =[[mailto:ex_ample@ex.com][ex_ample]]= is expected to export
to =\href{mailto:ex_ample@ex.com}{ex_ample}= but instead, we get
[[mailto:ex_ample@ex.com][ex_ample]] exports to (in latex): =\href{mailto:ex\_ample@ex.com}{ex\textsubscript{ample}}=
Note that a similar issue is seen with the HTML export.
* Reproduction
Export this file: =C-c C-e l p=.

By default underscore is treated that way--see the "Subscripts and
Superscripts" section of the manual
(https://orgmode.org/manual/Subscripts-and-Superscripts.html).
Set the '^' option to 'nil' to get the behaviour you're after:
#+OPTIONS: toc:nil num:nil ^:nil
If you want a subscript anywhere, you can get that by using curly braces
(e.g., ex_{ample}).

Thanks, I was looking at the section on links.

Thanks for the tip and my apologies for the noise.

This is expected. You mixed URL part of the link and the description.
Link description can have same formatting as any other Org text.
So, underscores are indeed treated as markup.
