I have some text I want to linkify, which I can reasonably do with a regex (search for http/https or www) but I’m worried about XSS complications. What’s a safe way to do this in Perl?

Exactly what do you mean by XSS complications? Are you only concerned with JavaScript or do URLs of the form http://example.com/command?type=delete;who=sam etc concern you as well?
As for linkifying URLs, there will always be edge cases, but Text::Markdown worked pretty well on a variety of inputs when I tried it. You can use the urls method to preprocess the links.
